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

OK. solve this:
Person1: What was your wedding ceremony like , Abigail ?
Person2:My husband and I got married in a registry office with just two friends there as witnesses . But then we had three parties to celebrate .
Person1: Three parties ? That's quite a lot . That must have been expensive !
Person2:Well , since my husband and I are from two different countries , and we live in a third country , we decided to have one in each country . It wasn't actually that expensive .
Person1: Were your parents upset that they weren't there to see you get married ?
Person2:I would have liked them to be there , but they couldn ' t afford to fly out to see us , and we couldn't afford to fly out to see them , so they understood .
Person1: Did your husband's family get to meet your family ?
Person2:My husband's parents flew out to meet my family when we got married in my hometown , so that was great . Some people spend ridiculous amounts of money on extravagant wedding receptions , but we agreed that the wedding party should be less about money and more about family .
Person1: That makes sense . Did you go on a honeymoon ?
Person2:We waited until our one-year anniversary to go on our honeymoon to Africa .
Person1: You really didn't have a very traditional wedding , did you ?
Person2:Not at all , but we don ' t have a very traditional marriage either , so it suited us perfectly !

informal
