Just Smile :)

A smile costs nothing, but gives so much.  It enriches those who receive it, without making poorer those who give it. It takes but a moment, but the memory of it sometimes lasts forever. None is so rich or mighty that he can get along without it, and none is so poor but he can be made rich by it. A smile creates happiness in the home, fosters goodwill in business, and is the sign of friendship. It brings rest to the weary, cheer to the discouraged, sunshine to the sad, and it 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.  Some people are too tired to give you a smile.  Give them yours, as no one needs a smile so much as he who has no smile to give.   Author Unknown
