I have the neighbor from hell next door to me. He is a second home owner, and when he comes here, he thinks he is in Disneyland, and all the full time residents need to conform to his expectations, including me. I will not detail all the crazy things he has done, but one cost me $3000 to oppose his efforts to dig a trench across my property for his utility lines (there was a utility easement, but it had expired years earlier).
Then he called me up to complain about me cutting down a tree on my property that was 500 feet from his home, and not even visible from his house. That was the end. I blocked his ability to telephone me, and ignore his e-mails.
I call him "The Long Island Dentist" as he is a retired dentist. A very disagreeable person. When he was building his house up here, there was a labor shortage. His project fell behind schedule as a result, so he fired the contractor. Which accomplished nothing, other than to delay his project further. He wound up having asphalt shingles installed late in the construction season, and the adhesives did not bond properly. An early winter windstorm blew all his shingles off, and they were everywhere. The man is a fool.
