I had a similar run-in with a neighbour a street away who told me to stop letting my 8 pound dog pee on his tree and against the electrical box in his yard. I politely informed him that the end of his yard was about 12 feet short of where he thought it was, specifically 30 feet from the centre of the road, and that both the tree and the box belong to the Town.
He must have reported the exchange to his wife because she was mortified that he unloaded on me the way he did and she apologized to me. She said he even checked with the Town to see if I was right about his property line. I was, and it was probably a huge shock to him to find out his frontage is only half as big as he thought it was. We visit his/not his tree only about a third as much as we used to. If he’d just been nice about his request instead of sandbagging me long after he started to be bugged about it, I’d have apologized and agreed to stay off that grass (snow at the time) altogether, without ever giving him the bad news about his property line. I’ll stop tormenting him soon 😊
Is this a new dog? I remember your other one. 😢
