There was once a little boy with a bad temper (脾气). He often had fights with his friends. One day, his father gave him a bag of nails (钉子) and told him to hammer (敲) a nail into the fence every time he lost his temper. The boy listened to his father and did what his father told him to do.
The first day, the boy drove 17 nails into the fence. Then the number of nails became less and less in the following days. The boy found that it was easier to keep his temper than to drive the nails into the fence. Finally, the day came when the boy didn’t lose his temper at all. He told his father about it and his father asked him to pull out one nail each time he was able to keep his temper.
The days passed and the young boy was finally able to tell his father that all the nails were gone.The father took his son by the hand and led him to the fence. He said, “You have done well, son, but look at the holes in the fence. The fence will never be the same as it was before. When you say some words in anger, your bad temper will leave a scar just like the hole. Even if you say you’re sorry, the wound is still there. If you hurt a person with words, the wound is as bad as a physical one. Friends are rare jewels (稀有珍宝). They make you smile and feel happy. So never hurt your friends.”
Since then the boy had never fought with his friends. He learned how to get on with others and he never lost his temper again.
