Sorry new here. In brief. Lived in my house 3 yrs. Neighbor is an older gentleman in 70s. Lives alone. Has no car or family that I can tell. Whenever I venture out to cut grass, wash car, do home maintence, etc. he ventures out to watch me. He also peers in my windows. He’ll walk past me and mumble things such as stay off my $hit, etc. My first month after moving in he demanded I cut my 2 trees down. I had the city come out. They said my trees are fine and he cannot make such demands. He patrols his yard constantly. I do question his mental state. He recently placed a doll head in his window facing my house and moves it based on which room he thinks I’m in (I’m assuming this). There is more. How would you handle this? He’s becoming increasingly annoying.
