I live in the U.K in a very small rural village called Barton Mills in Suffolk. To be diplomatic I have changed the names of the characters described. My next-door neighbor is Kevan who lives there with his wife Rachael. The house next to that is where Rachael’s father Ron (70) who is a widower lives. I have lived here for 17 years and from the moment I moved in Ron has harassed me. He stares through my windows as he walks past my house and stares at my wife if she is in the front garden. I don't mean just having a look I mean staring to the point of twisting his neck like an owl to give it the maximum effect. It is definitely intended to intimidate my wife. My other neighbors call him Stretch for this owl like ability. If anyone comes to my house he will be outside my house peering round the hedge to see what's going on. He picks up litter in the street and pushes into my hedge as he goes by. He reports everything I do to the council and does the same to my other neighbors.
My other neighbor John recently built a conservatory on the back of his house with full planning permission and building regs etc and Ron still complained to the council about it even though he could not even see it. The council officer turned up at Johns house to investigate only to find every bit of paperwork in order.
I think the most important thing when dealing with someone like this is not to become like them so I refrain from comment, keep to myself and ignore him completely which is a far more diplomatic policy than my neighbor Mark who just gives him the finger and stares right back. The harassment is taking its toll though so I wonder if you have any ideas.
