I had the bad luck to get a very religious classteacher and unfortunately I was the only kid not attending the religion class and well, after she found out our family wasn't christian she started putting me down in front of my classmates... I remember in my second year how I came late the second time (the first time I ran late to school was a few months before) and she went crazy over me coming late TWICE in a year. It was like ... I barely came late and she totally overreacted, even called me useless and lazy and whatnot. She definitely had some mental issues. But because of that a lot of other girls in my class started to pick on me just for making very humane mistakes, for example I once forgot to bring my math book and they made it out to be a huuuuge issue. Then my older brother, who attended the same school as me, confessed he was gay and that's when sh*t really hit the fan. They were some boys his age who decided it was time to beat him up and I just didn't want any of it, so I caught them before they could catch my brother one morning. I wasn't particularly brave or anything, I was just aware of the fact that since I partook in various different sports clubs I wasn't very scared of feeling physical pain and also I was pretty strong for my age. Of course I came out bruised and it wasn't a fun experience but my brother was... a wuss, to be frank. And someone had to do something. The teachers didn't care, by the way. We got them informed but... they gave some BS-answer that didn't even make sense and totally contradicted itself. Also, when my brother was punched in the face on the hallways my sport teacher walked by and acted like nothing happened. Like, okay.

Given how at that time I was always covered in bruises (hockey isn't a good sport for you if you are scared of injuries, LOL), my mom totally bought my "got these bruises from our last hockey match"-excuse and fortunately these homophobic bastards never tried anything ever again but yeaaah ... I was really mad at the teacher for ignoring the bullying. But that's how they handled bullying in general.
A few years later my brother told my mom what had happened back then and my mom told me she knew we were both bullied but that school was the only good one around us and that's why she didn't do anything about it. Well, too bad.
I must say, although school sucked most of the time because of the bullying, a few years later when I started to study I realized (especially after talking to a former friend who became depressed after being bullied) that I myself made peace with what had happened. I personally view what had happened as bad luck, and well, everyone has it from time to time, so did I. (Can't say how my brother views the whole issue though.) But at least I had some friends in my class - all the outcasts gathered around me, you could say, LOL. And they all thought our classteacher treated me unfairly but there wasn't anything they could do. So it wasn't all bad, despite the *mysteriously* losing things, getting ushed accidentally on a daily basis and all those other accidents.
A few years later my former classteacher was fired after our headmaster realized she was a bit nuts. There was some incident with one of her students, he got into a fight after some classmate stole his purse and even though our classteacher knew that kid had stolen from him, she refused to do something about it. She always had favourites, so that student must have been one of hers and that's why she didn't do something about it

So, hearing she got fired was kinda cool, though.
