You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues. You are required to assign a label 'formal' if there is an absence of emotion and a presence of questions anywhere within the conversation. If such pattern is not found assign the label 'informal'.

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 .

Person1: Hi , how are you doing ?
Person2:Everything's great . And you ?
Person1: Same here.Have you seen any new films recently ?
Person2:No , I haven't had a chance to . But I have been watching a Chinese TV scries called " Chinese-Style Divorce " .
Person1: Oh . really ? I saw it two years ago . It's worth seeing and it's thought-provoking .
Person2:Yeah . I found it is so close to our life .
Person1: It reflects some of our difficulties in this ever-changing world .
Person2:You said it . You know , the divorce rate has been on the rise in recent year .
Person1: Well , it's said that a lot of young people favor getting married quickly which tend to end quickly too .
Person2:I know a couple who divorced a week after getting married .
Person1: Oh , that's too short-lived .
Person2:That's true . It's said the short-lived marriage is typical of the post - 80s ' generation .
Person1: II can't agree more . The only-child-generation in China tends to know little about marriage .
Person2:Definitely.They don't take relationships and marriages very seriously .
Person1: In their mind , love is nothing but passion and marriage is over once the passion is gone .
Person2:I think , as the saying goes haste makes waste , it is the same with marriage .
informal

Person1: Oh !
Person2:What fools we were !
Person1: To think of it ! All my old silver ! It meant so much to me .
Person2:And my new car . To think that he simply drove off with everything in my car . That's what hurts me most .
Person1: What's so terrible too , is the fools we've made of ourselves .
Person2:I hardly dare call the police . They'll just laugh at us .
Person1: I'll never get over it . Oh , Harry , it was all so unnecessary . That man ! ! How could he do this to us after we'd put him up ?
Person2:And his story didn't even hold together . I feel such an idiot .
