Input:  Person1:     Ben , what are you doing ?  
 Person2:  Well , I would say that I ’ m just drifting - - here , in the pool .  
 Person1:      Why ?  
 Person2:  Well , it ’ s very comfortable just to drift here .  
 Person1:      Have you thought about graduate school ?  
 Person2:  No .  
 Person1:      Would you mind telling me then — what were those four years of college for ? What was the point of all that hard work ?  
 Person2:  You got me .  
 Person1:      Now listen , Ben . Look , I think it ’ s a very good thing that a young man — after he ’ s done some very good work — should have a chance to relax and enjoy himself , and lie around , and drink beer and so on . But after a few weeks I believe that person should want to take some stock in himself and his situation and start to think about getting off his ass .
