My neighbors don't like me. I don't like them. So they mock lie and slam doors. I was here first. I'm not moving it's expensive and I don't want to. I have memories of my late father lived here a couple years.
Why? Probably because they have pulled this on others before, and successfully got them to move away. You can turn the other cheek, as silly xtians will no doubt constantly advise, or give 'tit for tat'. Now you can try to find out why they don't like you, and remove the complaint by stop doing it, but chances are great they will simply find something else to whine about. I'd mock lie and slam doors more than they do, and find some other irritations to plague them with. For example, Google 'Liquid Stink', or 'The Mosquito Anti-Loitering Device'. Sounds like you are in a 'neighbor war' and nice guys finish last. Only outcomes are they drive you away, you send them packing, or they decide to coexist.
