Once there was a young boy who had a very bad temper. His father gave him a bag of nails and said that every time you got angry, you had to hammer a nail into fence.
The boy hammered 37 nails into that fence on the first day. The boy started to control his temper gradually over the next few weeks. The number of nail he was hitting into the fence slowly diminished. He observe that it was easier to switch temper rather than to hammer those nails into fence.
The day came when the boy did not lose his temper at all. He told his father and the father asked him that now you should took out a nail every day he kept his anger under control.
Finally, he pulled out all the nails from the fence. Now he told his father that all the nails were gone. The father asked his son to come with me let go to fence.
He said to his son. You have done very well my son, but look at the holes in the fence. The fence will never be the same. When you say things in irritation, they leave a mark just like this one. You can put a knife in a man and pull it out. It would not matter how countless times you say I am really sorry, the wound is still there.
The story show we should always control our temper, be careful with your temper. So choose carefully words when you are talking to someone, because words can wound. That may you regret later.
