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:     Thanks for inviting me to your friend ’ s wedding . I was surprised to hear the bride and groom talking to each other that way during the marriage ceremony . Is that common ? 
 Person2:  Well , some people use a standard set of words , but many couples today write their own wedding vows . 
 Person1:      Your tradition of throwing rice as they got into their car was interesting , but it didn't look like real rice to me . 
 Person2:  It wasn't . It was birdseed . We don't throw rice anymore because someone discovered that birds come along and eat the rice and have trouble digesting it . 
 Person1:      Oh , I didn't think of that . Well , this reception reminds me of weddingparties back in China . Plenty of food and drink , music and dancing , and interesting traditions . 
 Person2:  Wait until you see what happens next ! The bride is getting ready to throw her bouquet . Let's go over and watch . 
 Person1:      She ’ s got quite a crowd around her . Oh , look ! That little girl caught it ! 
 Person2:  She ’ s my friend ’ s ten-year-old niece . I guess there won ’ t be another wedding in this family for a long time .
