Once upon a time there was a very hot-tempered and unrestrained young man. And then one day his father gave him a bag of nails and ordered him to drive one nail into the fence post every time he could not contain his anger.
On the first day, there were several dozen nails in the post. The next week he learned to control his anger, and with each passing day, the number of nails driven into the pole began to decrease. The young man realized that it is easier to control his temperament than to drive in nails.
Finally the day came when he never lost his composure. He told his father about this, and he said that this time every day, when the son manages to restrain himself, he can pull out one nail from the post.
As time went on, the day came when he could inform his father that not a single nail remained in the post. Then the father took his son by the hand and led him to the fence:
- You did well, but can you see how many holes there are in the pillar? He will never be the same again. When you say something evil to a person, he will have the same scar as these holes. And no matter how many times after that you apologize, the scar will remain.
