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:       What seems to be the problem ? 
 Person2:Your secretary seems to think she is being harassed . 
 Person1:        What ? You've got to be kidding me ! 
 Person2:I wish I were , but i am deadly serious . She said you invited her to dinner last week . 
 Person1:        Of course I did . As recognition for a job well done . Once a month I invite the most productive employee to dinner . 
 Person2:Well , there is no problem there . But she seemed to think that you were angry when she refused , and that your motives are personal and not professional . 
 Person1:        I think she's misinterpreted my intentions . What happens now ? 
 Person2:Our harassment policy requires that we have a meeting with the HR manager and Miss Brown . It's quite serious . You could be reprimanded , or even fired if we find evidence that you were pressuring 
 Person1:        I understand that . But I hope that we can get to the bottom fo this and show Miss Brown that she misunderstood my reaction . 
 Person2:That's the purpose of the meeting . Sometimes a mediated conversation will straighten things out , and a little discussion and apology can calm the waters .
