Star, I don't mind really. I'm of the opinion that if they're a bit noisy now and then, then that leaves room for ( I was going to say - I can be noisy- but I know where that'll lead ) my house to be noisy every so often too. It is Monday I suppose, so I shouldn't complain.
I do think early hours is a bit inconsiderate unless its a one off party.
Several years ago my cow of a neighbour decided to start sanding down her bedroom walls at 7am on a Sunday morning. She was using an electric sander. She was nearly murdered that day!
