Smiling is infectuous

It is true! I smile even at strangers and there is rarely one who doesn't smile back.

Smiling Is Infectious
by Jez Alborough

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!
