Smiling is infectious, you can catch it like the flu.
When somenone smiled at me today, I started smiling too.
I turned around the corner and saw my own grin, When he smiled
I realized I had passed it on to him.
I thought about that smile, then understood its work.
A single smile just like mine, could travel round the earth.
So if you see a smile begin, don't leave it undetected.
Let's start an epidemic quick, and get the world infected.
