You can take a step you put, but you can never take back a word you say.  The damage is already done.

    There once was a little boy who had a bad temper. His father wanted to nip it in the bud. His father gave him a bag of nails and told him that every time he lost his temper, he must hammer a nail into the back of the fence. The first day the boy had driven 37 nails into the fence. Over the next few weeks, as he learned to control his anger, the number of nails hammered daily gradually dwindled down. He discovered it was easier to hold his temper than to drive those nails into the fence.... Finally the day came when the boy didn't lose his temper at all, he told his father about it and the father suggested that the boy now pull out one nail for each day that he was able to hold his temper.

    The days passed and the young boy was finally able to tell his father that all the nails were gone. The father took his son by the hand and led him to the fence. He said, "You have done well my son, but look at the holes in the fence. The fence will never be the same. When you say things in anger, they leave a scar just like this one. You can put a knife in a man and draw it out. It won't matter how many times you say ‘I'm sorry,’ the wound is still there." A verbal wound is worse than physical one. The physical wound may heal, but a verbal wound would never heal.  Friends are the best jewels you can ever possess since they make you smile and encourage you to succeed. They lend an ear, they share words of praise and they always want to open their hearts to us. Show your friends how much you care. ‘YOU ARE MY FRIEND AND I CARE Please forgive me if I have ever left a hole in Your fence.’
