is it normal at other schools,
to have your occasional bomb threat?
then when the cops come, nobody's
worried about the "bomb", but about the
drugs they need to get out of their lockers?
you hear the occasional gunshot and
sirens all afternoon?
car alarms go off alll the time?
fights in the halls highlight the day?
gang bangers walking past all the time?
IS THIS NORMAL?
