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'.

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: How did you get around over there ? Did you rent cars ?
Person2:No , that would be too expensive . We used the train system.We bought a special pass called a Enrail pass . It lets people use the train wherever they want , as often as they want .
Person1: I've heard about Enrail passes.So those Europeans really depend on trains a lot .
Person2:Yes , they do . I wish we Americans had a better train system .
Person1: I know . Our train system is lousy.And besides , Americans love their cars too much .
Person2:I agree . And probably the automobile companies are too powerful.They never allowed the government to develop trains .
Person1: It's too bad for the environment . So much pollution from cars .
Person2:Americans love cars for different reasons , I think.One reason is that we are very individualistic.And cars are a very individual way of getting around.Americans like the freedom of driving around by themselves.They don't want to ride in a train or bus with a group of people .
Person1: Yes , I agree . I think it is a cultural characteristic.It would be very hard to get us Americans to change this.But you know what ? Probably , in the future , Americans will have to change .
Person2:Why do you say " have to " ?
Person1: Because the earth's environment can't tolerate cars forever . I think cars are already causing global warming.When the problem gets more serious , world governments will have to start limiting car use .
Person2:Maybe you're right . They will have to develop alternative transportation.But it will be hard in America . Too many people are used to cars.Even in our movies cars are very important .
Person1: Wow ! I didn't notice the time.It ' s almost noon . I have to get home .
Person2:Do you want me to give you a ride ?
Person1: No , no problem . I have my car in the parking ramp around the corner .
Person2:Alright.Well , I'll stay here and have another coffee . Nice running into you .
Person1: See you around .

Person1: Have you ever run into a person who tries to bleed you white ?
