Okay, so let me try to tell this as unbiased as I can (will probably fail, though):
We've been living in this apartment for three years, and are getting along with all of our neighbors, including those on other floors (there are technically three floors, but I think the first-floor apartments are all vacant and are accessible through a different gate). We like to laugh and chat with each other until that neighbor and her family moved in.
At first, we thought she was nice, we all got along. Then one of our neighbors admitted she was saying something behind my mother's back. Even my mother's red flag radar was going off because our beloved new neighbor (we'll just call her BNB) was also saying something against that other neighbor.
So long story short, we stopped talking to her because what's the point? Then the troubles began. She'd post on Facebook and shade my mom, which we learned because people in our little village who know my mom are mostly friends of BNB too. Then she started spreading lies about me online, which was what really got my mom. There are no names but there are descriptions that make it obvious that it's about us.
One time, my mom passed by their unit because theirs is the first and ours is the one at the end, and BNB stretched her legs out and my mom frowned at it. And BNB had the unmitigated gall to say, "Why are you looking at me like that?"
That pushed my mom and they ended up in a shouting match. (LOL And then my mom and I also got into an argument, because I felt she shouldn't have tried to engage with that thing).
While a lot of people know and believe my mom (because she's an angel, LOL, I don't know how I came from her), there are also those gossipmongers who believed BNB. Lately, she's been stirring shizz again and then we realized, based from our other neighbor's story (who believed her for a short while and which damaged our friendly neighborhood relationship), that she's doing it on purpose.
She's really competitive; even said that if I was good in English, why didn't I argue with her in English? I'm trying to be nice but if I argued with her in English, she wouldn't be able to say a single thing. And I know it's a trap, one of her mind games; because if I truly did that, I would sound stupid and a tryhard to all the neighbors even if I can communicate in English.
Also, I wasn't taught and raised to treat others like that just because I don't like them.
Our other neighbor has also said that BNB would literally press her ear against the wall near our apartment unit to hear anything.
Girl's a psycho, and I fear a bit for our safety, but I know that if we ignore her, we'll cut her supply off of attention. Everyone in our apartment building seems to be wary of her.
She also recently got a warning from the landlord for tapping one of the other neighbor's kids and basically trying to intimidate him. Unfortunately for her, that kid is the landlord's nephew.
