Smiles!

 

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 it's worth.
  A single smile just like mine,
could travel round the Earth!

*the end.
