Every single Friday night our neighbour insists on playing loud music (well maybe it's not that loud but we're semi detached). Normally I wouldn't care but I have to go to work on Saturday at 4:30 in the morning. It goes on until about 11:30. I did speak to them once nicely and it stopped for a couple of weeks but started again.
I'm tempted to be petty and be really noisy Saturday morning in the hope they realise how selfish they're being. Would you be pissed off?
