Next door is a very very large extended family and I would expect they are severely overcrowded in there. This wouldn't bother me, they can live how they like but by god are they noisy!!!
There is constant banging, doors slamming, running stomping up and down the stairs, and what sometimes sounds like a football being banged around the house and against our walls. There is no let up of this noise, it begins at about 6am and finishes about 1am!
My partner has politely asked them to be abit more aware of the noise they are making and espessially at more unsociable times and they were polite and apologised but if anything its just got worse!
I literally want to bang the wall back in frustration sometimes but i know that won't solve anything and will just be very immature. but it might make me feel better
