Once there was a little boy who had a bad temper (脾气). His father gave him a bag of nails and told
him that every time he lost his temper, he must knock a nail into the back of the fence.
The first day, the boy knocked 37 nails into the fence. Over the next few weeks, as he learned to
control his anger, the number of the nails knocked gradually reduced every day. He discovered it was
easier to hold his temper than to knock those 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 the
father suggested that the boy now pull out one nail for each day when he was able to hold his temper.
The days passed and the 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, my son,
but look at the holes in the fence. The fence will never be the same. When you say things in anger, they
leave a scar (伤痕) just like this one. You can put a knife into a man and draw it out. No matter how
many times you say I'm sorry, the wound (伤口 ) is still there. A verbal (口头的 ) wound is as bad as a
physical one. "
