Question

A SMILE
(1) Smiling is infectious,
You catch it like the flu,
When someone smiled at me today,
I started smiling too.
(2) I passed around the corner,
And someone saw my grin,
When he smiled I realized,
I'd passed it on to him.
(3) I thought about that smile,
Then realized its worth,
A single smile, just like mine,
Could travel round the earth.
(4) So, if you feel a smile begin,
Don't leave it undetected.
Let's start an epidemic quick,
And get the world infected.​
