Our landlord has told us that a few weeks ago somebody made a complaint about noise from our house. Yes we have our share of arguments and sometimes they get louder than they should, but it's not exactly all the time. But we always apologise to our neighbour as soon as we can about it (end of terrace so only have one). Landlord said he doesn't know who it was. And obviously won't go accusing anyone. But aibu to say think that if someone had a problem they could and maybe should have come to us first and explained their concerns? Had they done we would have apologised and made sure we made a bigger effort to keep the shouting down. I'm a bit upset they went behind our backs about it. (Landlord isn't too concerned, but I am quite upset one of our neighbours did this).
