Definition: You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues.

Input:  Person1:       Hey , Maris , are you a part-timer ?  
 Person2:Part-timer ? Is that a new buzzword ?  
 Person1:        Oh , it ’ s pretty popular among my classmates these days . So are you ?  
 Person2:Sure , I have a part-time job as a bartender .  
 Person1:        Cool ! It must be amazing to work at a bar !  
 Person2:Yeah , but I ’ m not there for fun . I have to remain professional and if I get distracted , the manager would be pretty upset .  
 Person1:        That ’ s true . I ’ m wondering did you learn anything from the job ?  
 Person2:Of course . There ’ s always much to learn . I got to know more about the real world .  
 Person1:        You mean you got working experience , right ?  
 Person2:Not just working experience . I would say the biggest lesson I learned is how to deal with people from all walks of life .  
 Person1:        It must be very demanding .  
 Person2:Sometimes it is . But after working for a few weeks , it ’ s easy to figure out .  
 Person1:        Really ? It sounds interesting .  
 Person2:Maybe you can come to the bar one day and I ’ ll show you around .  
 Person1:        Great . I ’ m looking forward to it .
