A smile costs nothing, but it creates much :
It enriches those who receive it

It happens in a flash, and the memory of it may last forever.

None are so rich that they can get along with it.

It creates happiness in the home,

fosters goodwill in a business,

and is the countersign of friends.

Yet it cannot be begged, bought, borrowed or stolen for

it is something that is worth nothing to anyone until

it is given away.
