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:     Bob ! Your eyes look bloodshot . Did you not sleep well ?  
 Person2:  I had a drop too much last night . I attended a banquet given by a Chinese colleague of mine . And it was startling for me to find that people are forced to drink against their will on a Chinese table .  
 Person1:      You have it right . Alcohol is a medium for communicating emotion in China . Drinking with business partners or would-be friends is a way of solidifying friendship , especially in Northern China .  
 Person2:  I just felt embarrassed if I refused to drink when people toasted to me . But if I keep gulping down one cup after another , I'm afraid I would feel unfit or sick .  
 Person1:      You lose face by refusing to drink , and the host might think you refuse to give him face . The right thing to do seems to be drinking yourself into incoherence until you throw up . This will endear you to your friends .  
 Person2:  A few guys even threw a drunken fit last night , crying hoarsely and bawling whole heaps of nonsense that I never understood .  
 Person1:      Then he must be opening his heart to the friends . In a word , as long as you demonstrate a readiness to drink more in spite of already suffering extreme discomfort , no one will jeer at you .  
 Person2:  I got you . Next time . I'll preface a toast with a statement like ' I can't drink any more ' and then drink anyway .
