A smile creates happiness in the home, fosters good will in business, and is
the countersign of friendship. It brings rest to the weary, 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. Some people are too
tired to give you a smile. Give them one of yours, as none needs a smile so
much as he who has no more to give."
