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:     Hi , Bob , everything okay ? 
 Person2:  more or less . There's just one thing bothering me . 
 Person1:      oh ? What's that ? 
 Person2:  well , you know I have some students studying for their master's degree . One of them tried to give me a gift that kind made me uneasy . 
 Person1:      what gift ? 
 Person2:  it's an Egyptian carpet . The student came to my office the other day and brought the carpet to show his gratitude . Seeing what gift was , I was really uncomfortable . I mean it's too expensive a gift 
 Person1:      you refused the gift ? That's terrible . 
 Person2:  I know , but I really can't accept such an expensive gift . I explained to him why , but he seemed really upset about it . I think he might have taken it the wrong way . 
 Person1:      perhaps . He probably thinks you considered the gift a bribe for a higher grade . 
 Person2:  that's what I am worried about . I do understand the respect attached with the gift and I am honored . But I really don't think it's proper for a student to spend a fortune on a gift for a professor .
