Many years ago I had a "Gladys Kravitz" neighbor ( the nosy, obnoxious lady on Bewitched). She just had a grading personality, and really annoyed the hell of me. Seems, I never truly appreciated good neigbors until I got a bad one.
In the summertime, the crazy witch would actually press her face against my screen window and tell the kids to turn the tv down, because it was bothering her when she was watering her flowers.
She hated our beloved St. Bernard. One day I caught her spraying him (in the face)over the fence with some toxic insecticide. Well that was also the year her beloved rose bush garden died, and my half gallon of Round-Up weed killer disappeared. I never actually figured out what one of my daughters got up in the middle of the night and did the dirty deed. Was it right? Of course not, but she no longer had any need to be sticking her nose in our windows in the summertime, because nothing would grow where the roundup got spilled. Thank God we finally moved.
Forget about your idiot neighbor, we both know you can't fix stupid.
Be well, my friend.
