It costs nothing, but creates much. It enriches those who receive, without impoverishing those who give. It happens in a flash and the memory of it sometimes lasts forever, None are so rich they can get along without it, and none so poor but are richer for its benefits. It creates happiness in the home, fosters good will in a 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 fee trouble. Smile.
