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 ?  
 Person 1:Weed ! You know ? Pot , Ganja , Mary Jane some chronic !  
 Person2: Oh , umm , no thanks .

 Person1:        But I don't even know what to study . 
 Person2:If I had chance again , I'd major in English . You're good at language . 
 Person1:        That's what my parents want me to do . 
 Person2:You should take their advice . They know what's best for you . 
 Person1:        But my friends will have jobs and lots of fun , while I spend all my time doing reading and writing . 
 Person2:But if you go to university , you'll still have time for fun . 
 Person1:        Hm , what you say makes sense . But you know , I still have to ask my parents for pocket money , and I hate to do so at this age .

 Person1:        You're right . Thank you for the advice .
