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'.
Example: Person1:      Hey man , you wanna buy some weed ?  
 Person2:Some what ?

 Person2: Sounds good ! Let ’ s see , I want . 
 Person1:      Yeah ?  
 Person2:I want you to put your hands behind your head ! You are under arrest !

Example explanation: Based on the conversation, we can see that there is a presence of exclamation which is not present in a formal discussion. Therefore this is an informal conversation

Problem:  Person1:       This is the good life ! We have it good don ’ t you think ?  
 Person2:Yeah of course ! Although , don ’ t you ever wonder what “ could have been ” ?  
 Person1:        What do you mean ?  
 Person2:Well , sometimes I think of how things could have turned out if I had done things a little differently .  
 Person1:        For example ?  
 Person2:Like for example , if I hadn ’ t studied architecture , I would have become an artist like I wanted to .  
 Person1:        I see . Yeah now that I think of it , I wouldn ’ t have gotten married if I hadn ’ t moved to this town and met Sally .  
 Person2:You see ! Everything happens for a reason ! We wouldn ’ t even have met if I hadn ’ t been in that car accident ten years ago !  
 Person1:        Well , I have no regrets !  
 Person2:I ’ ll drink to that !
