Hi Matheous. Bit of a long shot, but is this it?
A smile costs nothing, but gives much.
It enriches those who receive it without making poorer those who give it.
A smile takes only a moment, but the memory of it can last forever.
None is so rich, or mighty, that they can get along without a smile.
And none is so poor that they cannot be made richer by a smile.
A smile creates happiness in the home, fosters goodwill in business and is the countersign of friendship.
A smile 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 of no value to anyone until it is given away.
Some people are too tired to give you a smile so give them one of yours as none needs a smile so much as he who has none to give.
