Dear Bored:
Unfortunately, events in your school are an accurate microcosm of real life, where after a brief shakeout period, you usually end up with the same people on the bottom, the same people on the top, and the same sadists hurting the same victims. Ask your teachers if you're allowed to hurt the same people in different ways; if that doesn't excite you either, you're probably not cut out to be a torturer in boring real life. At least, not until you've climbed high enough in the system that you can pick random new victims from well underneath you.
