IMO teachers say they care when it makes them look good, but I've always seen the teachers kinda ignore it happening or at least the stages, I have a general fear of hurting people lawl, and I won't retaliate unless I am hit in the head or the back, so I always just dealt with it, soemthing to realize in school was that, if someone was picking on you even a daily basis, you cannot fight back without punishment, you simply cannot, they would have to pull a weapon out against you in order to dodge repercussion, the first question they'd ask, are you alright? the 2nd question they ask, why didn't you tell the teacher? if you say you told the teacher someone usually talks to the teacher and they lie about it, then it somehow turns into you starting a fight..
IMO we can all be assholes sometimes specially on a bad day, but for someone that's an asshole on a daily basis I hope you have a slow painful death you asshole.
