It costs nothing, but gives much. You are
enriched when both receiving it and offering
it to someone else. It takes only a moment,
but its memory can last a lifetime.

None is so rich or mighty that
he can get along without it,
and none is so poor that he
cannot be made richer by it.

It brings happiness to the home,
promotes good will in business
and is the cornerstone of friendship.

It perks up the weary, brings cheer
to the discouraged, sunshine to the
sad and is nature's best antidote
for trouble.

It is so valuable, and yet it cannot
be bought, begged, borrowed or stolen,
for it is worthless until it is given away.

If you see someone without one of their own,
then send them one of yours: for no one needs
a smile so much as he who has none to give.
