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:       could we possibly discuss my salary some time ? 
 Person2:sure . 
 Person1:        first of all , I want you to know that I really like working for this company . Do you think I'm doing a good job here ? 
 Person2:well , you are a very hard-worker . 
 Person1:        I try very hard . The problem is , my salary just isn't enough to live on . Now that I have a wife and a child to support , we hardly have enough money for food and rent . 
 Person2:there are trying times for everyone . What do you propose ? 
 Person1:        I could really use a 5 % rise . 
 Person2:that's quite a bit . If I give you a raise , I'm going to have to give everyone a raise . 
 Person1:        listen , if you give me a raise , I'll take on extra responsibilities . 
 Person2:that sounds reasonable . How about this , from now on , you can be responsible for scheduling . That means that if you can't find someone to cover a shift , then you'll have to do it . 
 Person1:        that's fine . Do I get over-time for any extra hours that I work ? 
 Person2:of course . It's be against the law if we didn't . 
 Person1:        that sounds good to me . I really appreciate it . 
 Person2:you are welcome . Come in early tomorrow and I'll show you how to do the scheduling .
