It’s awful. It is so unsettling to be at odds with neighbors.
I’ve owned three homes and have never had an issue with any neighbors.
Right now I’m at my mother in law’s house. Her neighbor to one side is a real piece of work. He’s paranoid about his property line. He doesn’t like the absolute fact that my MIL’s property crosses his view of the river. My late FIL even caught him digging up the property line marker once.
I once accidentally strayed onto his property with the riding mower once. He came over and yelled at me for cutting his grass.
My son cuts the grass for my MIL. I told him to leave a 12” strip that he never cuts
