Thanks to everyone who gave advice about my situation with the neighbor. In the interest of NOT giving her any more ammunition to use against me in her private battle, I decided to delete the post. But I do appreciate the many comments I got. You were all, of course, correct. It's an unwinnable war, and I don't have the energy or desire to fight back. Anyway, thanks to all - I have some awesome commenters out there in the wide world.
Thanks especially to my Dr. Seuss-quoting commenters, who gave me quite a laugh today, just when I needed it. Here's one, back at you:
You’ll get mixed up of course, as you already know.
You’ll get mixed up with many strange birds as you go.
So be sure when you step.
Step with care and great tact
And remember that Life’s a great balancing act.
