AIBU here...my upstairs neighbour has their washing machine on about 3-4 times a day. When it spins the back two rooms of my property shake and are very noisy. I don't mind it during the day, but for the last couple of months it's still been on spin and drain past 10pm. Would it be alright if I asked her not to put a wash on so late or will I just be in for a mouthful of abuse? Are there rules for this sort of thing or is it a common courtesy to not do late night washing?
