Have a horrible neighbours (UK) to deal with.
He use to have a few guest comes to his house once in a while. And they will park anywhere they want and even block my driveway. Told them they should park elsewhere other than in front of others driveway and they are not happy about it. Every few weeks he will wash his cars and use the jet washer to blow trash and leaves from his area to the front of my house. I first thought it is just the wind. But after a while, it seems to be a very consistent thing that is happening so got a cctv system and confirm it is his doing. I don’t mind people keeping their place clean but NOT by throwing the trash to other people’s front door.
