If you smile when no one else is around, you really mean it. – Andy Rooney

Smile at each other, smile at your wife, smile at your husband, smile at your children, smile at each other - it doesn't matter who it is - and that will help you grow up in greater love for each other. -Mother Teresa

A smile succeeds when a thousand words might fail.  

A smile is never an ending but always a beautiful beginning.

A smile can open doors that were securely closed.

A smile is a curve that can straighten out a lot of things.

If a smile had to be bought, not even the very rich could afford one.

Smile, it increases your face value.

A smile gently hugs the heart of the one who receives it.

Smile...it's the second best thing you can do with your lips.

Smile - it makes people wonder what you're thinking.

No present could bring more joy to open than the one filled with your smile.
