Behind a smile?

Do you ever wonder what people are feeling when they smile?
Do they smile, because they?e happy? Or do they smile because they
want people to believe they?e happy? Maybe they smile because they
want you to smile and be happy?
A smile can touch a persons life in ways you can never imagine. It's
infectious and can cause a chain reaction. It can be memorable to
someone you pass on the street or the mall or driving?nd it only takes
a split second to smile and forget, yet?o someone that needed it, it
can last a lifetime.

Maybe I should smile more often.
