Smiling is infectious
You catch it like the flu
When someone smiled at me today
I started smiling too
I walked around the corner
And someone saw me grin
When he smiled I realised
I had passed it on to him
I thought about the smile
And then realised its worth
A single smile like mine
Could travel round the earth
So if you feel a smile begin
Don't leave it undetected
Start an epidemic And get the world infected.
