He told the boy, “The nails were your bad temper and they were hammered on people. You can remove the nails but the holes in the fence will remain. The fence will never look the same. It has scars all over. Some nails cannot even be pulled out. You can stab a man with a knife, and say sorry later, but the wound will remain there forever. Your bad temper and angry words were like that! Words are more painful than physical abuse! Use words for good purposes. Use them to grow relationships. Use them to show the love and kindness in your heart!”
Moral – Unkind words cause lasting damage: Let our words be kind and sweet.
