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:     How was your date recently ? 
 Person2:  Not too bad . It is seemingly too hard for me to find a place for our date . 
 Person1:      I guess so . Going to watch a movie and having dinner at a restaurant are usual . 
 Person2:  She said she wanted to go Dutch in dating . 
 Person1:      Yes , now many girls want to be independent , so it is a little popular , especially among white collars . 
 Person2:  But I am still traditional , so I felt weird when she paid for herself . 
 Person1:      Forget about it ! 
 Person2:  Are you satisfied with your girlfriend ? 
 Person1:      It will be a long story . We have many differences , for example , she usually puts all her clothes into washing machine . That is the sort of thing I can not bear .
