Smiling is infectious, you catch it like the flu, When someone smiled at me today, l started smiling too. I passed around the corner, and someone saw my grin, When he smiled l realized, l’d passed it on to him. l thought about that smile, then l realized 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 an epidemic quick, and get the world infected!
