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'.
Q:  Person1:       It smells like an ashtray in here ! 
 Person2:Hi honey ! What ’ s wrong ? Why do you have that look on your face ? 
 Person1:        What ’ s wrong ? I thought we agreed that you were gonna quit smoking . 
 Person2:No ! I said I was going to cut down which is very different . You can ’ t just expect me to go cold turkey overnight ! 
 Person1:        Look , there are other ways to quit . You can try the nicotine patch , or nicotine chewing gum . We spend a fortune on cigarettes every month and now laws are cracking down and not allowing smoking in any public place . It ’ s not like you can just light up like before . 
 Person2:I know , I know . I am really trying , but I don ’ t have the willpower to just quit . I can ’ t fight with the urge to reach for my pack of smokes in the morning with coffee or after lunch ! Please understand ? 
 Person1:        Fine ! I want a divorce !
