A smile costs nothing but gives much. It enriches those who receive without making poorer those who give. It takes but a moment, it sometimes lasts forever. None is so rich or mighty to get along without it. And none is so poor as not to be made rich by it.
A smile creates happiness in the home and business. And it is the counter sign of friendship and it brings success to the poor, and also brings sunshine to the sad.
Some people are too tired to give you a smile so give them yours, for no one needs a smile as much as one who has no more to give.
