Costs nothing but creates much.
Enriches those who receive,
Without impoverishing those who give.
Happens in a flash
And the memory of it sometimes lasts forever.
None are so rich that they can get along without it,
And none are so poor but are richer for a smile.
Yet it cannot be bought, begged, borrowed or stolen,
for it is something that is no earthly good to anyone until it is given away.
