Definition: You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues. If the conversation begins with a question, label it '1' otherwise '0'.
Input:  Person1:     Did you see the way that Brian came to work yesterday ? Ever since he came back from that conference in Silicon Valley , he's been coming to work dressed in jeans and sweatshirts . It's like he's decided to make himself at home in his office . I don't know how long it'll take before the management talks to him about it .  
 Person2:  He was really influenced by the way they do things on the west coast . I guess the working atmosphere is a lot more relaxed and casual in California . It comes from the information technology industry .. there isn't such a large division between home and office , so people want to work in the clothes they feel more relaxed in .  
 Person1:      Maybe so , but it seems kind of strange , which the rest of us in white shirts , dark suites , and ties .  
 Person2:  It's not as bad as that ... We are allowed to wear more casual jackets and trousers . Besides , didn't you hear what Brian found on his desk this morning ?  
 Person1:      What's that ?  
 Person2:  Management decided to give him four brand new white shirts . That's their way of telling him that his new style of dressing down is not quite acceptable .
