Smile, because if you do, they will.
Smile, because the sun’s shining.
Smile at that kid who looks sad---watch their face!
Smile, even when your boss doesn’t—they got their own shite to deal with!
Smile at the teenagers approaching you looking like they’re gonna rob you; they won’t!
Smile at your kids before you tell them they have done something wrong yet again---then maybe you won’t have to.
Smile for absolutely no reason at all. You will feel better for it.
Smile, because Mrs Brown fecken well said so!
NOW SMILE AGAIN AND TOO BAD IF THAT MEANS PEOPLE THINK YOU’RE NUTS!
