There was a boy with a really bad temper. In order to help him to control his anger, his father gave him a bag of nails, and said every time that you lose your temper, I want you to go into the backyard and hammer 1 nail into the fence.
On the very first day the boy hammered 50 nails into that fence. And over time the boy started to notice that he didn't need to hammer as many nails into the fence as he did the first day. He actually found it was easier to control his anger, than it was to go out and actually hammer nails into the fence.
Finally the day came where the boy didn't need to hammer any nails into the fence . He found that it is easier to control his anger than it was to go out and hammer nails into the fence. The father suggested that for every single day that he controls his temper he should remove 1 nail from the fence.
And after months, the boy was able to completely remove every single nail from the fence. And the boy was excited about this. So he brought his father out to the backyard to see that he had removed all of the nails. ***********
And the father said, you have done well my son. But look at this fence. It will never be the same. When you say things in anger, you leave a scar. You can put your knife into a man, and draw it out and say sorry as many times as you want but that wound will be there forever. The moral of the story is this control your anger don't say things in the heat of the moment that you may later regret. Its easier to remain patient and calm than it is to try to get forgiveness from someone who you have harmed....
