There was once a boy with a very bad temper. His father gave him one day a little bag with nails and told him every time he gets angry or fights with somebody to put a nail in the door.
First day he put 37 nails. Everyday, though the number of nails was digressing. He found out that it was easier to control himself, then to beat nails in the door.
Finally came the day no nail needed to be put in the door. Happy he went to his father and told him he didn’t loose his temper or fight with somebody and that day he didn’t put any nails. His father told him then to pull out a nail everyday he doesn’t fight at all. Some weeks have passed and the boy pulled out all the nails. Happier than before the boy ran to his dad to tell him.
His father walked with him to the door and told him: ”My son, you did good but look at all this wholes. It will never be the same. When you say something bad to somebody you leave a wound. No matter how sorry you feel inside his/her heart you already beat a nail. Controlling yourself is the most important.”

Forgive me for every bad word I said and for every nail I put in your heart. Things can never be same again but I will try to stop hurting you my love.
