what is a smile?

******a smile cost nothing, but gives much. it enriches those who give it. it takes a moment but the memory of it sometimes last forever.
******none is so rich or mighty that he can get along without it, and none is so poor but that he can not be made richer by it
******a smile creates happiness in the home, promotes good will in business, and is the cornerstone of friendship.
*******it can perk up the weary, bring cheer to the discouraged, sunshine to the sad and is nature's best antidote for trouble.
*******yet it cannot be bought, begged, borrowed or stolen, for it is something that is of no value to anyone until it is given away.
*******when people are too tired to give you a smile, give them one of yours. no one needs a smile so much as he who has none to give..
