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 realised, I'd passed it onto him. I thought about that smile, then I realised it's 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 and epidemic quick, and get the world infected.
