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: Hello , there . What can we do for you today ?
Person2:I received some leaflets in the post from you , one of them talked about a new service you have where you can transfer money between this bank and securities companies . Is that right ?
Person1: Yes , that's right . We have just introduced the program , but it's very popular already .
Person2:I also read that if the customer is a stock investor , which I am , it's possible to get additional benefits ?
Person1: Right again . We can provide a tailored consultation service for you , giving you the latest quotes from the Stock Exchange and help you to plan what exactly you do with your investments .
Person2:What if I don't want to come in to the branch , can I use the consultation service over the phone ?

Person1: I don ' t understand why you always look so happy , so energetic . It seems like you ' Ve got good news everyday .
Person2:Really ? Do I look happy all the time ?
Person1: All I know is you look quite differently from other teachers .
Person2:Oh , do you know why ? Actually , it ' s easy . Because I always exercise . My exercise , I think , is very hard . I often feel very good after conquering these difficulties . I feel alive !
Person1: Oh , I know . I saw you doing pull-ups one time on the campus and some students trying to imitate you .
Person2:Yeah , they are doing it for fun . Seldom would people like my exercise . It ' s difficult and boring .
Person1: It ' s true . Many students do the exercise when they have to . We have P . E . once a week .
Person2:But I think Chinese students need to exercise more . Besides exercise will help them learn new things better . Don ' t students want to have a good memory ?
Person1: Of course . I didn ' t know that . I only know exercise makes bodies stronger . I should take some exercise then . Do you have any suggestions ?
Person2:Well , do what you like to do . It can be anything . Jogging , doing aerobics , going bicycling , and playing ping-pong . Absolutely anything . Doing three or more workouts a week is good for you . But remember to do some stretches first .
Person1: Oh , I know . Thank you .
