Once a year our junior school headmaster would hand us all a small booklet of black and white photos. The booklet was full of happy little snaps of kids entitled "Sunny Smiles" and the idea was that we could sell our granny, extended family and neighbours one of the cute little shots - all the money going to children's charity. Trouble was, the smilers always looked to be having a better time than us and over night the booklets would be renamed "Grotty Grins." All those happy children now wore bad spectacles and shocking moustaches. I remember being smacked by a teacher who found my defaced copy of Grins. "How dare you scribble on the face of that abused child!" he shouted as he hit me again - which could only have been more ironic if he had been scribbling on my face as well punching it. Still, Granny bought a few from us and I have since become a highly skilled graffiti artist of some stature.
