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:       I wish our competition will quit poaching our people , when Susan resigned last week to work for the Sunburst , she was our fourth employee to leave us for them .  
 Person2:Have you ever considered that perhaps we have a morale problem among our employees ? If everyone is discontent with their work , of course they won't stick arround .  
 Person1:        Well , those do leave will soon find out the grass isn't as green on the other side of sense as they thought it was , I know Sunburst is suffering from inbreeding .  
 Person2:Inbreeding is a big drawback from snitching most of their employers from one or two companies .  
 Person1:        With Susan leaving , we should probably look to someone new on board .  
 Person2:Our human resource department is working on it , it's not easy to recruit new employees every few month , it's hard to find qualified people .  
 Person1:        Maybe we should start shopping around the competitors people .
