Smile!

"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 on to him.

I thought about that smile,

then I realized its worth.

A single smile just like mine,

could travel round 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!"
