Smile! It's Infectious!

 
You catch it like the flu.
When someone smiled at me today,

I started smiling too.

I passed around the corner,
and someone saw my grin.

When he smiled I realized,
I'd passed it on to him.

 

I   thought about that smile,
then I realized its worth.

A single smile just like mine,
could travel around the earth.

So, if you feel a smile begin,
don't leave it undetected.

Let's start an epidemic,
and get the world infected!
