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:     You are married to a foreigner , aren't you ? So what's it like ?  
 Person2:  Well , in the first year of our marriage , we had great difficulties in getting along . The things that are important to me are not important to him . We had a lot of conflicts .  
 Person1:      Yeah , I know what you mean . The first year of any marriage is difficult for all couples , not to mention two people from different cultures .  
 Person2:  Now we have a two-year-old boy . We're very happy that he's healthy and smart .  
 Person1:      Oh , so he's half Chinese and half American . That's unusual . What languages does he speak , then ?  
 Person2:  Right now he speaks mostly English , and he can say a few Chinese words . But he will learn in the future .  
 Person1:      What does he look like ? Can people tell ?  
 Person2:  Yes , people surely can . He's whiter than the Chinese kids , and his hair is a little blonde . My husband says his eyes are very Chinese though .
