"he says hold still in the dim afternoon and everything is blue instead of yellow and all the boys crack a smile and say how do you like being his dirty *****? some days i see the wrong person when i look at him or at any boy similiar. i say the wrong name, a name from the timeline of violence and wandering hands and go on with life and no one really gives it a second thought. any boy will grab my throat and say i'll show you what it feels like to hurt but i can't feel the back of my head and i'm wondering about that instead and there's blood on the goddamn wall again. and bad boys sure do hate it when other bad boys hurt their property. each boy takes credit, they drove me crazy but they always know that it was because of the one before, the one who was ten times more powerful than he could ever be."
