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!
