Once upon a time there was one very quick-tempered and unrestrained young man.
One day his father gave him a bag of nails and ordered him every time he did not keep his anger, he has to beat one nail into the fence post.
On the first day in the column were several dozen of nails.
The next week he learned to restrain his anger, and every day the number of nails hammered into the column began to decrease.
The young man realized that it is easier to control his temper than to beat nails.
Finally came a day when he never lost his composure, and he told his father about this.
The father said that this time every day when he will restrain himself, he can pull out one nail from the pillar.
Time passed, and the day came when he could inform his father that there was not a single nail left in the column.
Then the father took his son by the hand and led him to the fence:
“You did well, but do you see how many holes there are in the pole? He will never be like before.
When you say something evil to a person, it remains the same scar as these holes. And it does not matter how many times after that you will apologize – the scar remains.
