"Laughter is the shortest distance between human hearts.

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

I passed around the corner,
And someone saw my grin,
When he smiled l realized,
I’d passed it on to him.

l thought about that smile,
Then l 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!"
