There was a man who cared more for money than anything else, one day he sent his son to buy a box of matches, and told the boy he must see that every match in the box was good, soon the boy came back. The man took out a match and struck it, but it failed to light, he tried several more, but none was good. He got very angry and said, “I told you every match must be good, didn't I?”
“是的,你确实说过,”孩子回答,“我把盒子里所有的火柴都试过了,每根都能划得燃。”
