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'.

[EX Q]: Person1: Hi Mary , how's it going ?
Person2:Well , last night I had a big argument with Ann .
Person1: Terrible . It must be something serious . You two are such close friends .
Person2:Now that I look back at it , it wasn't that big a deal . I shouldn't have lost my temper .
Person1: Really ? What happened ?
Person2:It's just we've been planning to go the beach for a while , and we decided we could both make it this weekend . Then out of nowhere she called me up , said her boyfriend had made plans and that she need to cancel the trip . I was so angry when she told me that I said she didn't care about our friendship at all .
Person1: That's pretty harsh .
Person2:I know , but I was so upset . I mean , come on ! Does she have to do everything her boyfriend says ?
Person1: You know she probably feels just as bad .
Person2:Well , I think I was being a little selfish myself . I know they don't get to see each other very often .
Person1: Well , in that case I guess maybe you can be more understanding . You shouldn't let a trivial thing like this stand in the way of your friendship . After all you can go to the beach anytime you want .
Person2:Yeah , I'll call later to patch things up .

[EX Q]: Person1: Hey , Jordan , is that you ? Long time no see !
Person2:Oh , hey , no kidding ! I haven't seen you since orientation three months ago ! So how've you been ? Settling into college life OK ?
Person1: Yeah , I think so ! I pledged Phi Iota Alpha , so I'm living at the frat house now .
Person2:Oh , so you're a frat boy now , huh ?
Person1: Yeah , yeah , I know , it's totally cliche , but really , I think it's been a good decision . I've got a lot of support and good suggestions from the guys . What about you ? What have you been up to ?
Person2:Not much . I'm still living at home and commuting to school . I ended up dropping that metalworking class I was so excited about . It just wasn't as interesting as I'd hoped . The guidance counselor suggested that I focus on my prerequisite courses so that I can make sure the credits count .
Person1: That sounds smart ... but kind of boring .
Person2:Yeah , it is , a little bit . I joined the Great Outdoors Club , though , which has been a lot of fun . We've gone on two camping trips already , and I've made some good friends .
Person1: That's cool . Hey , so have you decided on your major yet ?
Person2:Definitely pre-med . What about you ?
Person1: I still have no clue ... but we don't have to declare a major till our sophomore year , so I've got time ! Oops , I'm late for class . Gotta run !
Person2:OK , take care ! Hey , nice running into you !
Person1: Yeah , you too !

Person1: I think I got it on Saturday , but it just showed up today .
