Definition: 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'.
Input:  Person1:       Welcome ! Welcome to Little Italy . We're the most Italian family here ! 
 Person2:So I've heard . That's why I'm having such a great time . 
 Person1:        If I hadn't married an Italian man , I probably wouldn't be pregnant so often . And maybe I could raise pigs instead of bambinos ! 
 Person2:Huh ? Um ... well , it's nice to see that some people still have big families . 
 Person1:        It is nice , but it would be nicer if my macho husband would get off his tush and help me . Ha-ha ... Have this . It's from Italy !
