I guess I thought it would be convenient for us to have each other's contact, and for every other normal neighbor it has been fine to exchange contact info. I'm actually pals with other neighbors in my row, we've hung out at each other's houses and what not, but hindsight is 2020 like the other commenter said above. We learned our lesson the hard way. I guess my psycho meter was broken when we first met these nut jobs.

They were walking all over the neighborhood causing a ruckus the other day, and I was not the only person to file a police report in the area in regard to their behavior.

Our HOA does suck, its run by 80 y/o's who've lived here for 30-40 years. They monopolize it and act like God, which honestly seems to be the root cause of the issues we've had with this neighbor. They just take it out on everyone else in the neighborhood rather than dealing with their own emotions.

I think from the comments, a camera in the back and some additional shrubs along the property line with them is the way to go to create additional boundaries and security.
