I have SUPER religious neighbors. They hang signs for the local church camp on their property ect. They kept putting our garbage cans in our driveway. While it was stupid and annoying it became more and more aggressive, they would trespass on my property and do damage to my house. But I could never catch them in the act.
So I did the only thing a sane person would do, I put on my velvet ritual cloak and made a show of putting a salt circle around my property, chanting and carrying on.
Never bothered me again.
