The Smile Starter!

Smiling is 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 to him.

I thought about that smile,

then I realized its worth.

A single smile just like mine

could travel the earth.

So, if you feel a smile begin,

don't leave it undetected.

Let's start an epidemic quick,

and get the world infected!
