The Value of a Smile

Smiling is infectious

You catch it like the flu

When someone smiled at me today

I started smiling too

I walked around a corner

And someone saw my grin

When he smiled too I realized

I’d passed it on to him

I thought about this smile of mine

And realized what its worth

A single smile begun by me

Could travel round the earth!

So if you feel your smile begin

Don’t leave it undetected 

Let’s start an epidemic now

And get the world infected
