A smile cost nothing but creates much. It enriches those who receive without impoverish in those who give. It happens in a flash and the memory of it sometimes last forever.
None are so rich they can get along without it and none so poor but both are richer for its benefits. It creates happiness in the home, foster good will in a business and is the countersign of friends.
It is rest to the weary, daylight to the discouraged, sunshine to the sad and nature's best antidote for trouble. Yet it cannot be bought, begged, borrowed or stolen, for it is something that is no earthly good to anybody until it is given away.
Nobody needs a smile so much as those who have none left to give.
