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'.
Example: Person1: Hey man , you wanna buy some weed ?
Person2:Some what ?
Person 1:Weed ! You know ? Pot , Ganja , Mary Jane some chronic !
Person2: Oh , umm , no thanks .
Person1: I also have blow if you prefer to do a few lines .

Problem: Person1: I am kind of nervous .
Person2:Nervous ? Why ?
Person1: I don't know . I never went to a church before . I was not raised as a Christian , so I don't know what to do .
Person2:Don't worry . You don't have to do anything.All you have to do is listen . You will enjoy it .
Person1: Maybe . I know I agreed to go with you , but now I don't feel right about it .
Person2:Listen , Ryan.Catholics welcome people who aren't Catholics to visit the church.You don't have to pretend to be Catholic . It's okay if you just come to listen .
Person1: Really ?
Person2:Yes . We are kind and welcoming people.It is not a secret society or something like that .
Person1: Alright . But will we sing ?
Person2:Yes , but you don't even have to sing . If you want to sing along , you can .
Person1: I don't know the words .
Person2:There is a songbook . All the words are in the songbook.Many people have to read the words .
Person1: And will I go up to the front to have the bread and wine ?
Person2:No . That is something only true Catholics do.So if you come to the church as a visitor , you only listen to the service.But you shouldn't go up to the altar for the bread and wine.Only after someone joins the church , then they go up for the Eucharist .
Person1: Eu-char-ist ? What is that ?
Person2:That is the special word for the ritual of the bread and wine.The Catholics call it the Eucharist .
Person1: It doesn't sound like an English word .
Person2:It's not . It's an ancient Greek word . It means gratitude .
Person1: Alright . Well , I feel more comfortable now.Now I understand I am welcome as a visitor .
Person2:Of course you are . I wouldn't ask you otherwise .
