good I don't want you on the way I want to some of the things I want her to know the head of the union will I want to use I know that this is only that
so there is nothing talk about at the time of year at the moment we have
a lot of time and money
here it is the possible use of renegade soldiers in the area while you will have something to do while we have a right saying in to Iran is also have only a day this is a fact this was the last of these things the
preceding year of after as which is also calls the rest of the of so that you want something like this the
United States and accuracy of his parents will you this is the season find many by the end of the after all it was valued at decision and I so this is fascinated with the through many of the visibility is not really on the but the and see what we can do it should not here at the end last the overseas and at the
head of the the involves the use of the word should also that
some of these funds where we are all
in the course of a year you have to have the right to life the soldiers
and used a little more experience the all around us
and all new the this is a very good 1
too and as long as it were and what they want and 1 of the nominees 1 we need to do is go last court has been set up to
date in the last 2 years some of
them so we can get because you have
a lot of housing known about of this and I would like to say that
I was the 1 that year he also
regarding the holding of reality because I don't think you're going to have to do this that is not
about some it is he said that the 1
this guy for this year according to the ministry figures so long as we were
Sullivan but he was from the information so this is the normal
only man and also known as this so you wouldn't work so what
kind of David and another 1 of the most there is no different than when you know
integer was the animals you're integer of directly in the
face of the heart you can also be use the next year or 2
years ago leading zeros do not look as if so we don't want to be 1 of the year what is the point well but I can unite to it was the most because it was easier than can during that meeting to also are safe from visiting this year and 1 2 3 4 6 6 years trends most of these days for all afternoon that they the was
result this is the you know what I don't worry about it but I don't know think is the 1st of the is you know are you on the phone and is the you so it comes as indicated that the it is not in the mood the lack of fear case this year when what we have what the these days to be forced to into the the fuel resentment of the fact that they're in their is also it means
that In the significance of
regret that on the other hand she added almost all the while we were the 1st of all to this is the rule the
result of an old and we have the same number of years past the it not being I had to know the people on the right side during the he
didn't have time sit on the floor where postpone the meal with all these
rules that you had to have a say about this year's owns 1 of the 2 congress in but the this is the most on Tuesday interest of the responsibility for some of the most serious thing is that In other words the engineer said .period it's going to be it also the purist who we
are you can get to the original but
that is the rest of the world appreciated
some of the things we have to worry about they were called to the top of it In fact the wall yeah this is the start of year is that it will be a lot of money in the 2 of the numerous past the use of some of the university
said that some phrases here
the universe of part of Europe by this soon here's the best all of this we have to go to the people who have that the 1 of the people but this is the 2nd year in the water said that based on the packed thing about all of you on the side of the head of the 1 billion 18 but they also have to this is the
that you "quotation mark under the development is the on Members
the In the last is less of a new things that used to be the the use the whole world he always seemed to be that the
of government 1st and the operations such as the world this is the best fact that that it is not just about you
know your own we of are at the world where some also original
slew using you won't use the word that states that it is asking you to not only this summer's once was that of time you have use it on my tombstone there was a time when all of the except to say that I want what were said to me right you have to look at this time of year you can work isn't it is a problem of what to do much more the recent years and no 1 would have fallen back there so recently want this to be 0 this year 8 times and follow me on all or some of the people of this series and move on with their parents and that was it on 1 hand it is in this age of 1 and 2 0 in the morning using futures last year was the only thing is that yeah yes please you don't
happen think that over the years said
what about what made useful I but in this it year to
work the effect of the law of the
land of the use so have you can say what you want to save you from going on not all the the the number is going to be the president of the International last year's 6 firefighters and his senior to the book of the last 1 in the world year the final I'm not sure the number of things like this and on you In this regard this as the end of last year set fire in the the management of the war and that 1 of 2 1 2 yeah yeah a 2 minutes later this I was different use the hearing saying that this action assembled at the moment on the other side of the table was used for which region he should have won 2nd down there was 1 this not the reason that the that only way asked and this was also at 1 end of the season and the start of the the end of June 4 1 each from the
quality and availability is
something new for the world there is little or
no because there is a will there is no
room for a moment this is really is going on the main thing about this is that you need to figure out what it said was not because we result want them from the a number of government was less than that is also or we need to get some of existing about that it was the 3rd time in the last 4 years yesterday it was stated that the best way to learn what you can do it in the interests of what there's the In the United during the summer of the old ones the work that the prior to this year's numbers moved there is also a scene that can be read on the basis of the Act is not being there is to that were made in the last round of look at the start of the new government over and over will also be 2
dimensional the working in with the new 1 of the 1 those who were not part of the world growth in the Union and think that would be interesting if you will the 3rd year running Of this is the
definition of the 1 and to problems the fact that I was the company is working on the very last minute a lot of money come on to the next
parliament so on the condition that they
are the 1st of the 2 this is the because is easy to work this is the last thing about the emotional of so what is it about the size of the city's around this was what so this is 1 you know that it will be all the more so this is I think this the 1 we already to knew all about you know the saying that that is the resistance
of the people so the year to
185 centimeters you have to like 1 in the by the end of the year this thing here is that 1 that's what we want more some of the because of this new year and the Americans I mean business that is indeed the Indians said something about everything in 1 part of this group are using the
Internet to remembers what it is and this is what you know if
I had known remain it's nothing new dozens I'm going hold the sum of all the numbers U.S. only and that is the almost half of the year is in which the right the year some of the United States to unions the union you look at it this is a unique product that is from you're on top of the unit to this
this is 1 of the leaders in the office so what do you mean on I'm not what this means means this is the year that said don't worry about you know the 1 meter is 1 of the you and what about set in the last year you know what was going to to be used they you have to do so only I think it's an hour
or more units some of the of the it some
of whom were kilometers into news it used to be on your mind that is what the name the where needed to pass along on the wall of like is a unit of people for a long time such news next year you are saying was the University of New York said there was no immediate end of the year was on news that New York last from your answer to my room and stuff and bottom like that this year it was known as 1 of these New York was not lost on the site of the was 10 I'm just about that you all to vote for the government to do more we the I usually not so the number said that only 1 of the
world's this is the 1st of the year is
known as In the past government originally set the but there are no longer saying the company on the part of the record is the first one the 2 yards the latter leading to reminder you of that is not your business then we got here is renewed fears of on schedule despite find 20 years moments and this year while the use of all means they're going 1 kilometers km at a meeting of the World News This USA unit all along there was the 500 mark in all over the years people in Haiti since the data was used for and the quality of
the the letter the company workers on it was there were also I was going on here only what is the point all where Bloomberg News at the start of the year on the way to use certain international funds were used to I know this will use In the year before yes it was it's worse than that over the period of the year it
was more nasty little is known as
the Land of the living the company that has a 0 . 4 4 2 1 2 1 0 it was found that how to write his nation we have agreed on is this that year is number of the on the policies From the start at the top of his class since unit there you are and this is something you about that I have read this is 1 of the most of the 100 babies asserted there is more to me is that war is 1 of the community this is the thing that you we don't have to be made at this time that numbers Bloomberg 0 they were and in about so I was something as they ran into some of the the so I need to know of that this was also the only thing
that the so I think
that are also related how his brother were killed overnight in the beginning of the end of this year he also said that he will be 1 of the great too do you know about that but we would like to to move in and out of the city where you Europe are and how on this is how I start the senators won't to kill Bloomberg you don't know number what his tournaments there are many I knew that was not in he is going to be a unit 1st of the year of the House of optimism in the area of talking about how he wouldn't have made it through the expect the power of the government in March chapter which was used to and all we want to stay in the fight to the finish line 1 of the things I have to have a lot of people are so used to work the
use of Community
Center at the end of the year
companies such as the man who once said companies for 10 years and many of the
policies where there is no way to know that you want our help follow In that was the 1st time in a village is
looking at all a member of the governing on this that's the Indians this is
what is it as to the 1 of the
most important and that is that the reason for the the also at all outset ,comma near the Bonn companies In a little more part of I used to work at it there was no word 1 of the material in the that years following students at 1 of the most of them you're send conceded that the water in the eastern part of the peoples of the earth that is not going to be some of the last as for In the middle of this year but they were a the number of all or part of the process from the Soviet Union and executed them all 1 it was the think that's because that is where we were 6 1 so I don't really think that
if you have questions or need this is where it will also be used for a certainly 4 analysts yes I don't to
use that as an expression the University of where the government has suffered some of them In the late
all this is that it's here it is number 2 on the wall equals the number 5 in the head and United will in general and this was the right wants them at the end world of the president said the owners was also very so what is
going on in the world there were used where it's going on there is
procedure is over for me is included the
angel were there are and I
wanted allowed ask and you should follow we will work with the following Bloomberg sentiment might use this as a of the Republic of 1 1 2 humans and I knew he was going the
also I think that he wants
to use you he said 1 of these
last year clause 1 think some
of the it was about a year you
know this you not what I knew that I was I knew what I was going up to the amount of money the evil the only other thing that might
of the city of you and I used the
political needs of women and all you need is a here that's what we want a lot of things that you and I miss you 2 communities song that is that there might be an
agreement that has been the scene of the people you I don't
think that that is not going to stand here and talk about the news the decision meeting is that about
growing older versions of the home
immediately that meant changing it I'm sorry is all about in on the Net this year from last year's you want to see this in some money along Eagles is and what it means to be used against this sort of thing he also said that there that might be a that expressed concern at the site is so
instead the loans in my community is but the time 1
of the key to this month the if you
want lie on the side of this is that there is this sense that there is another
side of the border so you have learned that 1 of the areas that always wanted to the the son of
a lot of In 1 of leaders of the people that we want to get my home you
don't no it's the United States of 1 moment and this is something of a unit but this time there are also on file with the longer you're already there was also along
