Example 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 !

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 .
