As annoying and frustrating as it is, you can only control your own behaviour, you can't control any one else's. But if you feel very strongly about it, would you go so far as to report them to the police? And if you did, would they do anything about it? And how would that affect your neighbourly relations for the future? Personally, I'd rather say nowt and let your neighbours get on with it, but it's your choice.
The OP did not say she was considering reporting them or saying anything. She said she was p***ed off and some of us can empathise with that. We know we can’t control the behaviour of selfish people but their behaviour can end up affecting us so we’ve à right to feel annoyed by that. She is NBU
