     Bill worked in a big office in the city, and he usually went to the barber's (理发店)

during working hours. This was against the rules. Office workers had to have their hair

cut after work. While Bill was at the barber's one day, the manager (经理) of the office

came in to have his own hair cut. Bill saw him and tried to hide his face, but the manager

came and sat beside him, so he recognized (认出) him. "Hello, Bill," said the manager.

"I see that you are having your hair cut in office time." "Yes, sir, I am," said Bill. "You see,

sir, it grows in office time." "Not all of it," said the manager of the office at once. "Some of it

grows in your own time." "Yes, sir, that's quite right," answered Bill politely (礼貌地). "But
