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: Hi , Fanny .
Person2:Hi , Andy .
Person1: Are you feeling OK ? You sound a little tired this morning .
Person2:I did not sleep much last night . I really feel bad . It was a crazy night .
Person1: What happened ?
Person2:I had a bad dream . I was walking alone in the graveyard , and suddenly all the ghosts jumped out of their graves . They began to chase me through the graveyard and shouted that they wanted my blood .
Person1: Oh , what a nightmare ! Then what happened ?
Person2:My mother woke me up . She had heard me crying out for help .
Person1: You have got a great mother .
Person2:I felt embarrased . After all , I am 18 years old . Mom gave me some chocolate cookies and a glass of milk .
Person1: That sounds good !
Person2:Yeah , but i was afraid to fall back asleep . I am worrying about getting into the University of Michigan .
Person1: Me too . But I tell myself that if they don ' t accept me , another school will .

Person1: Are you excited about your trip next month ?
Person2:Yes and no . I can ' t wait to go to Europe , but at the same time I am terrified .
Person1: Why ?
Person2:Well , I have acrophobia . I have a chronic fear of flying .
Person1: Oh really ? I have an uncle who is also terrified of flying . It ' s not that bad though , I mean , it is pretty scary to be in this big machine flying through the air at seven hundred miles per hour . I actually have arachnophobia .
Person2:You ' re scared of spiders ? I actually have two more phobias . Acrophobia and glossophobia .
Person1: I guess that explains why you are afraid of flying , but public speaking is not that bad .
Person2:Are you kidding ? When I get on stage , my palms start to sweat , I get really nervous and I can hardly speak .
Person1: Well , I must confess I am a bit claustrophobic . I hate being in an elevator for more than 5 seconds .
Person2:We are such weirdos right ?

Person2:You ' re right . I wasn ' t . I hear nothing .
