All I can say is woooow!
You mean to tell me your relationship with your nieghbor is that petty. Rather than intrude 6" one way or the other, ya'll are going to drive each other crazy.
In the 35 years I have lived in the same residence, I have had one nieghbor couple, he now deceased, she moved away. Best friends I ever had, adopted my kids as their surigate grand children, adopted the dog as their own. They were trusted fully and completely. Were their at a momments notice. I miss them terribly.
The home is now up for sale, it does cause me some anxiety, but I hope to be as good of a nieghbor to the new owners, as the old owners taught me to be.
Now I got one guy that lives 1/4 mile down the road, ever since he cussed my wife, while we were repairing a gate, he best not cross my path. But that's a whole nuther story, and petty it ain't.
