Smiling is infectious
You catch it like the flu,
When someone smiled at me today
I started smiling too.

I walked around the corner,
And someone saw me grin.
When he smiled, I realised
I’d passed it on to him.

I thought about the smile
And then I realised its worth.
A single smile like mine
Could travel round the earth.

If you feel a smile begin
Don’t leave it undetected,
Start an epidemic quick
And get the world infected. (Anon.)
