smile is a gift that anyone can give it costs nothing, but saves 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 is so rich that he can get along without it; none so poor that he is not enriched by it. it creates happiness in the home, fosters goodwill in business, and is the countersign of friends. it is rest to the weary, daylight to the discouraged, sunshine to the sick, and nature's best antidote
