The next time you question the value of a smiling face, consider these words...
A smile costs nothing, but creates much.
A smile enriches those who receive without impoverishing those who give.
A smile happens in a flash and the memory of it sometimes lasts forever.
None are so rich they can get along without a smile, and none so poor but are richer for its benefits.
A smile creates happiness in the home, fosters good will in a business, and is the countersign of friends.
A smile is rest to the weary, daylight to the discouraged, sunshine to the sad, and nature's best antidote for trouble.
Yet a smile cannot be bought, begged, borrowed, or stolen; for it is something that is no earthly good to anybody 'til it is given away.
For nobody needs a smile so much as those who have none left to give.
