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,
l’d passed it on to him.
l thought about that smile,
then l realized it’s 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!
