Oppressed? That's a stretch. Brats, thieves, and vandals come from all kinds of socio-economic levels. Once it becomes cool to do something stupid, everybody does it. I really disliked my fifth grade teacher. So on a Saturday I made a huge cartoon of her on the white abode schoolhouse wall using black walnuts for a nearby tree. I thought they'd just hose it off, and didn't realize how deeply that greenish black walnut husk stain goes. There were no phones in that area yet; but when I saw the school janitor pulling up the driveway the next morning, I knew something was up. He hauled me back to the school and handed me a scrub brush, a bucket of detergent, a paintbrush, and a gallon of white paint. It took me all day; but I sure learned my lesson.
