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: it seems the department still has some money left in the budget . Do you have any suggestions how to use it before the budget is renewed ?
Person2:what about renting a restaurant and treating the employees to a nice dinner ?
Person1: but we've done that many times . We want something fresh this time .
Person2:okay , let me think . What about a party-and-movie night ? We can rearrange our reference room , invite a band to play some music , order in some food and watch a movie later .
Person1: sounds like a good idea , but a band sounds too expensive .
Person2:well , we can ask people to make small contributions .
Person1: I don ' t think so . I don't think people are going to like it if they have to pay to come . But we certainly can cut costs in other ways , such as make the party BYOB .
Person2:BYOB ? What's that ?
Person1: bring your own beverage . We can provide food , but people have to bring their own drinks .
Person2:so we're just going to have a party where they bring their own drinks and we just give them some snacks ? I don't know how well that will go over .
Person1: maybe you have a point . How about having a party on a Friday afternoon ? We'll stop early , order some pizza , and serve drinks . There'll be music but no band . Having the party in the office will make
Person2:oh , that sounds like fun !
Solution: formal
