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:       Come in , come in !  
 Person2:Hi , Gary , what happened ? I was waiting for you at the theater . Why didn ’ t you meet me there ?  
 Person1:        I thought we were supposed to meet HERE .  
 Person2:Don ’ t you know our movie starts at seven ? And we were going to meet at the theater at five to seven . Then it doesn ’ t make sense to meet at the apartment .  
 Person1:        I ’ m sorry . We must have misunderstood each other .  
 Person2:Why don ’ t you try to be clearer about your intentions ?  
 Person1:        You ’ re right . I am sorry . Let ’ s go and watch the movie .  
 Person2:It ’ s okay . I don ’ t want to go now . We ’ Ve already missed ten minutes of the movie . I don ’ t want to see a movie without watching the beginning .
