It costs nothing,but creates much.It enriches those who receive,without impoverishing those who give.It happens in a flash and the memory of it sometimes lasts forever.It brings the rest to the weary,the daylight to the discouraged and the sunshine to the sad.Yet it can't be bought,begged,borrowed,or stolen,for it is something that is no earthly good to anybody till it is given away.For nobody needs a smile so much as those who have none left to give.
