WHAT IS A SMILE?

It costs nothing but creates much
It enriches those who receive it,
without impoverishing those who give
It happens in a flash and the memory of it sometimes lasts forever.

It is rest to the weary, daylight to the discouraged,
sunshine to the sad, and is the best antidote for trouble
Yet it cannot be bought, begged, bemoaned or stolen
It creates happiness in the house
