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:       So , Emily , how was your day ?  
 Person2:I don't think you really want to hear about it .  
 Person1:        It can't have been that bad . Go on and tell me about it .  
 Person2:To be honest , it was horrible ! My manager is such a pain in the neck !  
 Person1:        Why ? What happened ?  
 Person2:Well , he made quite a few mistakes on the monthly report and when his supervisor found them , my manager blamed them on me !  
 Person1:        That's not very fair . What did you do ?  
 Person2:There wasn't really anything that I could do . There's always been a lot of bad blood between my manager and myself . If I had said anything , he would have fired me for sure .  
 Person1:        Does he treat everyone in your department like this ?  
 Person2:He treats everyone pretty badly , but the way he treats me really takes the cake !  
 Person1:        Do you have any idea why he treats you worse than the others ?  
 Person2:I really have no idea . All I know is that the thought of him really curls my hair !  
 Person1:        Is there anyone else you can talk to about it at your company ?  
 Person2:Not really . I'm hoping to live with it for a while until I get a promotion .  
 Person1:        That's very sensible . It sounds like you have a good head on your shoulders .  
 Person2:I try to be sensible about it , but it's not very easy . Sometimes you just have to grin and bear it .  
 Person1:        That's so true . When you have a taste for success , you can't let dishonest people like your manager get in the way .
