saying "Thanks a feckin lot for the Oasis fest you enjoyed till 5am! Maybe you could be more considerate of your neighbour next time. And while we're about it could you and your girlfriend not have your rows at 6am and when you're not rowing could you ask your girlfriend not to squeal during sex!!!!"
To be fair, they didn't wake the baby but they did wake me and I have enough trouble sleeping as it is. Also the music/party thing doesn't happen that often, the rows are a bit more frequent tho.
You'd think victorian terraces would be a bit more noise proof.............
