Next door had a party yesterday from about 1pm until midnight. It was very noisy- braying women, feral children and the tv on so loud I could tell you what wsa being advertised.
Anyway, we were in our garden early on in the party and I heard her say that since the new neighbours arrived (that would be us) she really noticed how thin the walls are and therefore she made a real point of being quiet, probably too quiet, unlike her new neighbours.
We're renting a semi and have to put up with their tv blaring, loud children and the worst piano playing imaginable. Yes we are a bit noisy since I have a 3yr old and 1 yr old (and the previous inhabitant was a 90yr woman) but I think it's really rude to say this when we were within ear-shot and at the start of an 11 hour party that was hardly quiet.
I can't even think of a way to get her back because we can't be too noisy of an evening due to our children.
