At Katie's school, Ther Kidz thought that it would be nice to have a graffiti wall. And, after due representation and consideration, the school agreed that a graffiti wall they should have.
So they employed a graffiti painter to come to the school and paint the graffiti wall with graffiti.
And here it is.
Katie did run past some of her fellow pupils the idea that maybe a graffiti wall should be a place for free expression. By... Ther Kidz.
"Oh, we'd only make a mess of it," one of them said.
