Definition: 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'.
Input:  Person1:       Matthew , do you know much about body language in countries around the world ? 
 Person2:Sure , I've picked up a few things from travelling around for work . Why ? 
 Person1:        Well , I had a meeting today with a woman from Japan and she wouldn't stop bowing ! I didn't know what to do ! 
 Person2:Did you bow back ? 
 Person1:        No , I tried to shake her hand , but her hand was so limp I was a bit offended . 
 Person2:Well , Japanese businessmen and women typically bow to greet each other in Japan . She might have been offended by your strong handshake . 
 Person1:        But she was in America ! Shouldn't she have known that strong handshakes in America signify confidence and respect ? 
 Person2:Things are different in Japan . You know , in some countries , making eye contact with others is considered rude . 
 Person1:        Is that why she wouldn ’ t look at me in the meeting ? 
 Person2:I think it's highly possible , yes . 
 Person1:        The meeting really didn ’ t go down well at all . I think I need to read up about intercultural communication before I have another meeting with someone from another country . 
 Person2:That's a good idea . When you don ’ t know much about other cultures , the simplest thing can offend someone . 
 Person1:        That's so true . It's great that we see eye to eye on this .
