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 , Natasha , how's life ? 
 Person2:  Great . My family came to visit me . 
 Person1:      Oh , you must be very happy . How many people are there in your family ? 
 Person2:  My immediate family is very large . It's my mother , my father , my two older brothers , my younger sister and me . 
 Person1:      I have a small family . They are my parents , my younger brother and me . 
 Person2:  I thought you were the only child in the family . Didn't China practice the only-child policy in the early 1980s ? 
 Person1:      Yes , it did . But my parents are ethnic minority people . It's a preferential policy for an ethnic minority family to have two children . 
 Person2:  Interesting . What do you think about families with only one child ? 
 Person1:      The child must feel very longly . My younger brother is 10 years younger than me . Before he was born , I used to be the only child and always dreamed that I would have a younger sister or brother one day . 
 Person2:  Do you get along well with each other ? 
 Person1:      Yes , we are very close . He is 12 years old now and very smart . He always makes us laugh a lot . 
 Person2:  You are very lucky to have such a nice family . 
 Person1:      Thank you .
