The value of a smile

It costs nothing, but creates much good. It enriches those who receive it without impoverishing those who give it away. It happens in a flash but the memory of it can last forever. No one is so rich that he can get along without it. No one is too poor to feel rich when receiving it. It creates happiness in the home, fosters good will in business, and is the countersign of friends. It is rest to the weary, daylight to the discouraged, sunshine to the sad, and nature's best antidote for trouble. Yet it cannot be bought, begged, borrowed, or stolen for it is something of no earthly good to anybody until it is given away willingly.
