Smiling Is Infectious 
Smiling is infectious,
you catch it like the flu,
When someone smiled at
me today,
I started smiling too.
I passed around the 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 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!
