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 that 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
Lets start an epidemic and get the world infected.  (Author unknown)

So which three people would you make smile and why?
