There once was a little boy who had a bad temper. 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 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. Make sure you control your temper the next time you are tempted to say something you will regret later.

We should be careful with what we're saying. Sometimes words gives a big impact when you don't realize it. It may hurt peoples around us. No matter how many times you apologize, it still hurts. Although he/she would say "nevermind nevermind nevermind" and accept your apology, but it actually still hurt that person deeply. Perhaps he/she is giving chances for you to correct your mistakes. Hoping to see changes in you to a better you. So, appreciate the chances. There's no one will always say 'Nevermind' and forgive you for your wrong doings. Someday later, he/she may get fed up and leave you. Instead of repeating your apology why don't you reduce chances apologize to people?   So, becareful with your words <3
