Beautiful story (The story of the boy and the nails)

There was a boy who was moody and was constantly losing his temper. His father gave him a bag full of nails and said to him:
My son, I want you to hammer a nail into the fence of our wooden garden every time you get angry and lose your temper
So the boy began to implement the advice of his father ....
On the first day he hammered 37 nails, but it was not easy to insert the screw into the fence.
He began to try to take control of himself in anger, and after a few days he would knock less nails, and in weeks he managed to control himself, and stopped the anger and the knock of the nails. His father came and told him about his accomplishment. A day passes by you did not get angry.
The boy began to remove the nails on the day when he did not get angry until he finished the nails in the fence.
He came to his father and told him to do it again. His father took him to the fence and said to him, "My son has done well, but now look at those holes in the fence. This fence will never be the same.
When you say things in an angry state, they leave traces of such holes in the hearts of others.
You can stab a person and withdraw a knife but it does not matter how many times you say 'I'm sorry,' because the wound will remain.
I wish the story you like
