Smiling is infectuos;
you catch it like a 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 realised
I'd passed it on to him.
I thought about that smile
then I realized it's 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 quick, and get the world infected!"
