Sorry everyone for the late response, I had no notifications for this thread until this morning! Some of these responses are amazing.
Some context -
After over a year of trying everything I can to stop my early 20 something neighbour screeching, shouting and being insanely loud every single night, waking myself and my DS up at all hours. She's a gamer which is fine but every night I hear "FUCK, FUCK, FUCKKKK!! ARGHHHHH, NOOOOO" constantly with things being thrown around and things being smashed. Honestly, I've had it. Tomorrow I'm playing something at full blast by her bedroom wall, on repeat and leaving the house for the day and night. I've been kind, I've tried reasoning, ive tried being firmer, nothing has worked. We're moving when our fixed term is up so can't move at the moment.
Neighbour has no conditions or valid reasons to be like this other than she's obnoxious and selfish. Had a party night before last until 2am on a Thursday night. I could still hear people after 3 am. I can't put DS cot or our bed anywhere else either. I've resorted to sleeping downstairs in the living room with DS regularly to escape the noise.
I know it's petty, and I might not actually have the guts to do it, but I don't care anymore. If I do it, it won't affect anyone else nearby, just her. It will just make me feel better for a day 😂
