you had recently enrolled to a new school, originally your dad was hesitant when he heard it was a mostly colored kid school. He's not racist. But he used to go to these schools, and since he grew up in a crappy city there were crappy kids who were racist towards kids who weren't completely colored. He didn't want you to face that. He knew how mean those kids could get

After some convincing from your step mom he gave in and let you go. It's a few days in this new town, so far the kids seem nice. Sure theres a few druggies, but nothing like your dad had said. They were really nice for some big bad kids that most describe. You couldn't help but wonder what's so big and bad. But oh well
