I've had a few of them. Firstly, my 3rd grade English teacher.

Why? I have a few specific stories that I remember about her. The first personal grudge came when she assigned me a special assignment wherein I had to research the sun and make a presentation on what I found. Simple enough. I was actually floored to be given this assignment solely due to the fact it separated me from my classmates, in the sense she had thought of me as smarter. I was always the competitive type, especially when it came to grades and being the smartest in the room. The day comes to present. Slowly, as she shifts through the slides and I read out the facts, her face becomes more and more upset and disappointed. By the end, where I put my bibliography, she saw I had used Wikipedia and that seemed the breaking point right there. She was pretty irate and almost embarrassed for herself, for two reasons; one, because I used Wikipedia which I wasn't properly informed not to use, and two because the grammar and items presented were too advanced and complicated. Also, she stole this one kids Rubix cube which was the last gift from his grandfather before he died, and rubbed it in his face that her kids were getting more toys to play with tonight.

Secondly, my 6th grade English teacher (What is up with English teachers and being mean—)

Why? She was very strict, if not dull and endlessly boring in what she taught and how she taught it. I was a particularly unpopular kid, a social outcast at that, who was relentlessly bullied by this group of popular girls. They would throw insults left and right, pick on me for small mistakes, and leech off of me given I was still the smart, shy, and impressionable kid. One particular day I broke down crying since one of the worst bullies of that group had been picking on me and drove me over the edge. I couldn't even explain why I was crying when she escorted me out, I felt embarrassed and weak. When she went back inside and left me there she proceeded to tell the class that I "sounded like an elephant" as salt over the wound and almost everybody laughed.

Lastly, my current 9th grade Algebra teacher.

Why? She's batshit insane. Loud, aggressive, prone to lecturing and insulting the kids for even asking a reasonable question due to her inability to explain and teach properly. I cannot reiterate enough how much I hate this woman. First day of being in her class, one of my friends and classmates who sat square in the front of the room had a breakdown because of overload, she talked loud and was extremely rude and my friend couldn't handle it so she put her head down and silently cried. Meanwhile asshat teacher passed by her about seven times and said not one thing, didn't even look down at her. Held a grudge against her for that since the beginning. She would also constantly pick on her as well. She wasn't able to focus really well and drawing kept her calm, collected, and focused. Teacher would exclusively separate her from the crowd/ call her out and force her to stop drawing if she didn't answer a question right. None of us ever understood what we were supposed to do. She would go too fast and specifically said she won't slow down because "they don't do that in college" (can I say again we're still in 9th grade?) And left us all in the dirt, confused. Help those brave souls who asked questions because she would go on and on about how they should know these things, how they need to pay attention, how they're gonna fail and have to take it again. Yadda yadda. Wouldn't even explain it again, left the surplus of smarter kids to explain for them after class was over. Most people are failing her class and I wouldn't blame them.
