She's a teacher from where my older sister works at. Let's call her 'Anne'. Generally, she ain't good.
There's a small private high school located in our hometown. Me and my siblings all attended there and graduated. Its a common knowledge for everyone there that if you are an alumni of the school, the school principal can allow you to teach there as a part time job, or a job you can have while studying for board exams or while looking for other jobs. Overall, its a place where alumnis are welcome to work at no matter what job they are actually aiming for (as long as you are qualified for the job)
My oldest sister who is in her final year of college (she always aimed to be teacher) started working there as a good way to gather teaching experiences or something.
Anyway, Anne rented a place where ironically, my cousin lives in. The actual owner of the place kindly took her in after she got somewhat ostricized from her hometown (I wonder why...) and now works as a teacher at the school because our school principal took pity on her.
She made the staffroom a hellish place. She made the house she lives in an unbearable place to stay in. During family get-togethers, my sister and my cousin shared to us what they endured.
Generally, Anne is just a freaking narcissist, even talking over the school principal during staff meetings and complaining too much to the landlady. She complains about problems she face that are actually her doing in the first place, and refuse to accept the fact that those problems starts with her. She is often heard by my cousin making a ruckus in her kitchen trying to cook...at 8 or 9 pm. She demands answers from my cousin why her faucet isn't working, why the lights are out and so on. He's really getting concerned about it, especially since he and his wife have 3 kids who are also starting to get distracted from her noise.
Not only that, but her classes are slowly turning to hell. My younger cousins who are attending the school started to skip her classes because they can't tolerate her and just stayed in the library among with some of their classmates, reading. They admitted they can't even understand what she's teaching and just resorted into them studying on their own. Even the school principal lost her cool and practically dragged Anne out of their home.
That's just a few that stuck to me.
