Definition: You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues. You are required to assign a label 'formal' if there is an absence of emotion and a presence of questions anywhere within the conversation. If such pattern is not found assign the label 'informal'.
Input:  Person1:       Do you have much experience with kids ?  
 Person2:Yes . I have three sons . Actually I also have a grandson .  
 Person1:        To tell you the truth , sometimes I regret having a baby so early . I have been making so many sacrifices just because my husband insisted on keeping the baby .  
 Person2:I understand . I was in your position before . At that time I couldn ’ t depend on anyone taking care of the children for me . My husband seldom stayed at home .  
 Person1:        What about your mother ? Did she help you ?  
 Person2:Yes , she did a little . But you see , Americans are different from Chinese . You can ’ t depend on your own mother to be a full-time babysitter . She could baby-sit only once or twice a week . That ’ s it . I had to care for them most of the time .  
 Person1:        I see . So if my little family goes to America , I would end up taking care of my child all the time . My husband would have to make the bread for us . I just don ’ t know how I would get some education and be able to get a job some day .  
 Person2:Don ’ t worry . You can take night classes . I did that when I had kids . And soon your child will be old enough to attend kindergarten . Then you could find a job and work .  
 Person1:        Sounds not so easy to me . When that happens , I will be too old to learn .  
 Person2:No . You see , I went back to school to get my Master ’ s Degree when I was in my thirties . You won ’ t be older than that .
