[Q]:  Person1:       So , is L . A . all it's cracked up to be ?  
 Person2:Well , the stereotype in the movies is that L . A . is a frivolous town with a lot of flaky people . I guess , in the back of my mind , that's what I expected .  
 Person1:        And , is it what you found ?  
 Person2:Well , it is and it's not . The city of L . A . is much bigger and more diverse than I had expected . There are people here from all over the country and all over world , like New York . I've heard people say that in L . A . , everyone is from somewhere else . Tha's partly true . So , I've met all kinds of people here . What I'm realizing is that the picture of L . A . that's in movies only represents a small segment of the city .  
 Person1:        You're right . Life isn't always like the movies . 
[A]: formal


[Q]:  Person1:       Who will meet you at the airport ?

[Q]:  Person1:       Hello Michael . 
 Person2:Hello Todd . 
 Person1:        We're going to talk about Australia . Or your going to talk about Australia . So first of all how any people live in Australia ? 
 Person2:Australia ? Oh , there's about twenty million people in Australia right now . A little bit under , but close to twenty . 
 Person1:        OK . What are the biggest cities ? 
 Person2:The biggest city ? The biggest city is Sydney , then it's followed by Melbourne and then Brisbane and then I think it's Perth . But most of the big cities are on the East Coast of Australia . And Perth is on the west coast , but sort of of out there by itself . 
 Person1:        OK . Um , if you had to live in one place where would you live ? 
 Person2:I like Brisbane . I had my teenage years in Brisbane , growing up in Brisbane , um or maybe Sidney because it is a big city , but Brisbane has got the gold coast and the sunshine . 
 Person1:        Oh , nice . Actually , what is the capital city of Australia ? 
 Person2:Ah , Canberra is the capital city . But is not the biggest city . Sydney is the biggest city . Canberra was made sort of by the politicians so Sydney wouldn't get to crowded . It's a separate territory .
