Just moved into our own flat after many many years of renting/saving. Outskirts of London, zone 5, which explains why we’ve bought a flat and not a house, a flat was what we could afford. But it’s a nice place. Not a new build, for context, but not really old either. 70’s I think. We are on the ground floor. Above us live a single mum and her teenage son.
We’ve only been here three nights but have been kept up until 3am or so by what was quite obviously someone using headphones and shouting into a mouthpiece. DH was a gamer so I knew what was going on. Think ‘NOOOOOO!!!’ And ‘FUCCCCKKKKKKKK’ at random intervals. It’s incredibly loud.
We have a 3 month old baby. Sleep is obviously precious enough as it is, he still wakes 2/3 times in a night to feed.
Anyway, this morning we popped upstairs and the mum answers the door-explained that we just moved in, can hear all the shouting, please can it stop because it’s a very unsociable time of night to be dealing with that level of noise, we have a baby, DH has work etc etc. She was very apologetic and said it was her 15 year old son playing Fortnite, and she went to sleep with ear plugs in but that he wakes her up a lot too.
But then she said there wasn’t much she could do because her son has ASD, it’s his hobby and only way of being sociable as he games with others online, he considers these gamers his friends so he won’t be able to stop doing it. She said in time hopefully we’ll ‘filter out’ the noise. He gets carried away and he doesn’t do it on purpose but she said again about his ASD and repeated that that’s the way he is and there is nothing she can do. Then she said we hope we have a lovely Christmas and closed the door 
Now, I know this is Mumsnet and I’ve been here a long time. So, before anyone asks-
No, we can’t ‘move bedrooms’
No, we can’t move
No, we can’t afford a detached house.
But surely we shouldn’t just have to put up with it?! They’re having a laugh right?
