The Integrity of a Smile. 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 goodwill 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 for trouble. Yet it cannot be bought, begged, borrowed, or stolen, for it is something that is no earthly good to anyone until it is given away. And if in the course of the day some of your friends should be too tired to give you a smile, why don't you give them one of yours? For nobody needs a smile so much as those who have none left to give!
