Working in a international company in New York, Bill used                
to go to the barber's during working hours to have his hair                         
cut, which, of course,∧against the rule: Office workers had to                 
have their hair cut in their own times．While Bill was at                           
the barber's one day, the manager came in by the accident to                       
have his own hair cut．Bill tried to hide his face immediate                       
he saw the manager, but the manager recognized himself．When            
asking why he was having his hair cut in office time,                                
Bill said calmly, “It grows in office time.” “No all of it,”                          
said the manager．“Some of it grow in your own time.”                           
“But I am not having it all cut off.” Bill replied.
