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'.

Let me give you an 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: I also have blow if you prefer to do a few lines .
Person2: No , I am ok , really .
Person1: Come on man ! I even got dope and acid ! Try some !
Person2: Do you really have all of these drugs ? Where do you get them from ?
Person1: I got my connections ! Just tell me what you want and I ' ll even give you one ounce for free .
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 !
The answer to this example can be: informal
Here is why: 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

Person1: My dear , it's five flights up !
Person2:That's all right.We ' ll get used to it.Besides , it is quiet up there .
Person1: We're little further away from the street and traffic noise
