A: My watch always gains ten minutes a day.

B: That's funny. My watch always loses ten minutes a day.

A: No kidding.

B: I am serious. Every morning I set my watch by the radio, but it still loses ten minutes.

A: You know what you can do?

B: Throw it away and buy a new one.

A: No, you don't have to. You only need to put your watch back ten minutes every day.

B: So you put your watch back ten minutes every day?

A: Yes, that's what I am doing.

B: Why bother? Just buy a new watch. It doesn't cost much. Besides, I just can’t put up with this thing any more.
