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:       I can't stand the stupid guy any longer.It ' s unbelievable !  
 Person2:Oh , my dear lady.Take it easy.You should forgive a green hand like him .  
 Person1:        He does everything so mindlessly that he is going to drive me crazy .  
 Person2:I suggest you talk with him and teach him how to deal with the problems .  
 Person1:        I have told him how to do it several times , but he's never listened to me .  
 Person2:Maybe you should communicate with him like a friend and not a boss .  
 Person1:        Oh , I always have difficulty in getting along with the staff .  
 Person2:Just take them for your good friends and have a talk with them as we do , make sure you don't lose your temper .  
 Person1:        I think that's a bad idea . I'd hate anyone here to think of me as a friend.How would they ever respect me as they can do whatever they want ?  
 Person2:I disagree . All you have to do is respect the staff and their opinions .
