I went next door at 3am this morning because my neighbour was playing very loud music and keeping me and DH awake. I live in a mid terrace, neighbour is on the end.
I had friends visiting with their DD and DS also in the house. I now know that all the adults in my house were awake from round 1am (when neighbour presumably came home from the pub) till I spoke to her.
When she answered her door she turned to her friend and said "It's my neighbour". I said "so you're aware you've got neighbours then. Her friend said "sorry, I'll turn it down" and went into the front room to do it.
I then said something along the lines of "if I wasn't pregnant and up in 3 hours for work I might've let it go but this isn't the first time you've done this. I presume your son isn't upstairs because if he was you'd have more consideration. You know I've got a baby so you should have some consideration for my family too. So turn the fucking music down.
She has done it a couple of times before including jumping up and down on a trampoline in the back garden (under mine and DS's bedroom windows) at 4am. But I have never openly complained about it. I'm not friendly towards her but I am civil, say hello when I see her etc.
I am moving in a few weeks so I felt less scared about complaining and feel bad to not address it before the new people move in here as they also have a young family.
So I know IANBU but am gutted I didn't really say everything I could have. What would you have said?
