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 .
