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 .
