My English-as-second-language teacher hated me because I kept correcting her spelling and vocabulary. But it was okay because I hated her right back and took every opportunity to annoy her (for the sake of rigorous accuracy, of course). Fortunately she couldn't actually harm or sabotage me because I aced almost all of my tests and had good scores in national ESL competitions, and a sudden drop in grades would likely have been too obvious.
The point where I'd had enough was a test about the anatomy of vehicles. She had crossed out my answer to "left side of a ship" because I'd written port or larboard (not that I expected someone with a master's diploma to know the etymology of nautical terms*, or not to confuse larboard with starboard because they looked similar), but what made my blood fucking boil was when she crossed out my answers of hood and trunk because I'd used the American words instead of the British bonnet and boot, and when I pointed out that she'd marked those same answers as correct in others' tests, she went back and fucking changed the scores on the other tests. I told her it was "deplorable conduct for a teacher" (approximate translation, and as polite as I was going to get that day) and she dragged me to the principal for disrupting the class.
That was the third year of high school (I think "junior" is the American equivalent). I took an option to graduate one year early from ESL, in part out of spite. I'm sure she was glad to be rid of me.
* I knew "larboard" and "starboard" and the names of individual sails from Assassin's Creed 4. Much of my vocabulary comes from games (including some Russian from STALKER, Metro, and MGSV).
edit: A resurfaced memory! Still regarding sailing -- she thought "in distress" meant that things were calm and safe because "di-stress" was the opposite of "stress". I swear I'm not making this shit up!
