Everyone needs a smiLe !

Smiling is infectious, you catch it like the flu,
When someone smiled at me today, I started smiling too.
I passed around a corner, and someone saw my grin,
When he smiled I realized, I'd passed it on to him.
I thought about that smile, then I realized its true 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 whole world infected!
