Smiling is infectious, you can catch it like the flu. When someone smiled at me today, I started smiling too. I passed around the corner, and someone saw me grin. And when he smiled I realised I'd passed it on to him. I thought about that smile and realised it's worth.
A single smile like mine, could travel around 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.(found in a cafe in Scotland, Author unknown), Henrietta, Sussex, England
