They allow you to play CDs in school? CD and tape players and radios are strictly banned at good ol' D.H. Conley High. Just doing their part to make school a less enjoyable and fulfilling place, I suppose.
My mother has been known to blast NPR when encountering people whose music is too loud. I often appreciate loud music, but not when it's going to bother others. There is such a thing as basic courtesy, after all.
