Neighbours are a couple in their 40s. They've had some sort of dinner party. Kitchen/dining room is at back of the house and they have big doors that are open on to the garden. They are making a hell of a racket with their guests. I have work in the morning. Am I unreasonable to be annoyed? When is unacceptable for that sort of noise on a week night. I could close my windows but it's uncomfortably hot and is a bit of a pain given I'm not the one making unsociable noise. Or am I over reacting? Maybe it's not so bad. What do people think?
