Q: 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'.
 Person1:       David , why don't you clean your room ?  
 Person2:I am not in the mood .  
 Person1:        Why are you feeling depress ?  
 Person2:I was told my girlfriend was speaking ill of me . It's a real letdown .  
 Person1:        I don't think she would do such a thing .  
 Person2:But she did and it made me disappointed .  
 Person1:        Oh , cheer up ! A girlfriend is not everything .  
 Person2:But she means a lot to me .  
 Person1:        Then forgive her mistake .
