"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!"
