Each waking moment is as a step on an endless path. Each step we take is fashioned from what has gone before. If we hurt someone, we can apologize, but we still have created hurt. If we hammer a nail into a tree, we can pull it out, but a wound to the tree remains. It is better to think before acting for not all acts can simply be wiped clean with an apology. Sometimes saying one is sorry may be the weak perfume that fails to cover up the overpowering bad odor of a deed.
