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'.

Problem: Person1: How do you think people get their personalities ?
Person2:I think it ' s mainly from the environment a person lives in .
Person1: Don ' t you think people get their personalities from their parents ?
Person2:No , but parents control a lot of the environment that kids grow up in , so they certainly influence their kids ' personalities a lot .
Person1: So why do you think many kids have personalities that are so different from their parents .
Person2:Maybe when they become teenagers , they want to be completely different to their parents .
Person1: You might be right . I guess most parents want their kids to be like them , but kids today grow up in a different environment . You know , they know much more about the world from the internet , newspapers , and tv .
Person2:Do you think that teenagers get a lot of their bad behaviour from tv and movies ?
Person1: Maybe some of it . I think a lot of people blame TV and movies when the real problem is that the parents aren ' t bringing their child up correctly .
Person2:Parents have a difficult job . They have to bring up their children and usually have to work too .
Person1: Yes , that ' s true . Your son is doing well at school , isn ' t he ?
Person2:Yes , he is . He ' s very hardworking when he ' s at school . Then he comes home from school and does homework before dinner . After dinner , he goes out with his friends .
Person1: So , he ' s not a bookworm ? It ' s good that he has an outgoing personality . Some kids are very quiet and introverted . You wonder they ' ll survive in the real world without their parents to support them .
Solution: formal
