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 don ’ t know what I ’ m going to do ! It ’ s going to be impossible to make ends meet if I lose my job !  
 Person2:don ’ t worry . I don't think you ’ re going to lose your job over one mistake .  
 Person1:        it was a rather big mistake . When you work as an investment adviser , ONC small mistake can cost the company millions .  
 Person2:but it wasn ’ t just you who was involved , right ? You were only doing what your supervisor told you to do .  
 Person1:        that ’ s true , but my supervisor is very dishonest . There ’ s no reason he needs to tell our boss the truth . I ’ m sure he will tell our boss that it was all my fault , and there ’ s nothing I can do about tha  
 Person2:let ’ s think realistically about what might happen . How much money do you have in your savings ?  
 Person1:        I have enough to live off of for about 3 months . But I really don't want to spend my life savings on just living ! I ’ d rather invest my money somehow .  
 Person2:well , that ’ s good . If you lose your job , you can just move in with me until you find another job . That will save you plenty of money .  
 Person1:        that ’ s very generous of you . I guess that would work .  
 Person2:if you lose your job , you just have to go for a few months without buying all the junk you usually buy . If you live frugally , you ’ ll save plenty of money .  
 Person1:        I guess working with so much money has made me rather greedy . Maybe losing my job would be a good thing !
