I won't mention her name here, but she was my Theology teacher in Junior Year (I went to a Catholic school, which honestly wasn't bad at all. Except for this teacher).
She was a horrendous teacher. I got the general impression that she cared more about drilling us with her stupid babbling than actually educating us and giving us the motivation to think for ourselves. But this is what *really* drove it over the edge:
At one point, I had a final paper due in an hour for another class (with a super-duper strict deadline), so I asked her if I could use her printer really quickly before class had even started. She told me no, even though she wasn't using it for herself. She asked me why I needed the printer. I said that I needed to print out a document. I figure, fair enough, and I don't press the issue. But then, she's all like, "Oh, a responsible student would've done it last night. Why didn't you do it last night?" Now, at this point in the school year, I already knew that I hated her, and I didn't want to explain that my printer at home was being a dick, and I had been planning to use the school library printers, except those were being dicks too. So, I tell her that it was "personal," and, by personal, I meant "none of your fucking business." She *assumes* that I'm going through some traumatic event in my life, so she basically tells me to talk to the school counselor. And I'm thinking to myself, like... WTF. That's not what I said. But I go to the counselor's office anyway (he's a guy I already know, and we're cool with each other), I explain to him the situation, and he's like "Oh, okay. You can use my printer." I use it, and when I get back to the classroom, she's all like "Oh, okay. So did you talk to him about your problem?" I was like "Sure." But then later, she says hi to my counselor and actually asks if I stopped by and talked about my problems. He tells the truth, "He stopped by to print something because of a situation, but he didn't really have any problems to talk about."
Now this is where the fucking ***** starts going way over edge. She starts harassing me and calling me at home, being like, "Tell me why you didn't print your paper at home. Did you really have a personal problem?" And I replied "Yes, I had a personal problem," and, once again, by personal, I mean "it's not really your business, stop asking me." She harasses me for 20 minutes on the phone, trying to get me to "open up to her" ("I'm here for you if you need to talk. I care about you. Blah blah blah.") and just keeps harassing me. It gets to the point where she basically tells me that *I'm* becoming a headache for *her* (*****, YOU'RE THE ONE CALLING ME AT HOME), and that I should seriously just tell her what the "personal problem" was. Simply on principle, I refuse to. Nobody should have the right to simply *demand* to know whatever problems are in my life, especially if the underlying presumption that it's something serious. She actually starts harassing my counselor too, basically asking him to break his right of confidentiality and start telling her about my problems. Eventually, because I refuse to tell her, she calls me a liar, and I get detentions for 2 days in a row.
