It costs nothing but creates much.
It enriches those who receive, Without impoverishing those who give.
It 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.
