SMILE

Smile costs nothing, but:-
Its memory lasts forever
It enriches those who receive
It creates happiness in the home
It fosters goodwill in a business
It can never be bought, begged, borrowed or stolen
It's the sign of friendship
It's rest to the weary
It's sunshine to the sad
It's daylight for the distraught
It's antidote for trouble
It's good only when it is given away
And
It's most needed by those who have no smile left to give
