The tree is a large pine, 80+ feet tall, and the lowest branches are 30 feet up and well above interference with anything, well away from the house and garage. If a branch fell it might hit the electrical drop from the alley to her house but it would have to be a lucky shot. The trunk is on my side so it is my tree.
There are more branches on that side vs. mine and if she removed several it would not be noticeable to the overall balance of the tree and it is so tall you really can't see the whole tree unless you are blocks away. There are 30 others just like it within the city block that no one is paying to prune, they are all natural. It has no gall and no insect-caused disease. Per the arborist who took down the other tree last year it is healthy. The reasons she noted were her concerns for her property couched in terms of "what is best for everyone" even though every reason was her own (wants to sweep fewer needles, that one branch on her side looks dead, it leans 3 degrees toward her property, etc).
There is a bit more to the story. During the first exchange about the tree I cheerfully mentioned that my adult daughter was moving back to this town from the big city after getting a new job, and that we were seeing many people leaving that big city now for political concerns and to reduce their cost of living. The neighbor said, "We can't have that, there is not enough housing to support that!" So that was really what got to me. Not only is she declaring what shall be done on my property with my money, but thinks she has a right to say who can move to her town. I left that exchange and stewed about it for 2 days and decided I have had enough from her and I put up the boundary and told her no on the tree. She was curt and had a very snarky "you are not doing what is good for you" attitude. Despite my being an exceedingly nice neighbor and very courteous, she turned on the bitch mode with this friction from me.
I have been a good and reasonable neighbor. Incredibly, she tied my blackberry bush to her side of the fence so she could get the berries this year (she admitted that) and I said nothing. One of my sprinkler heads was turned toward her lot so it would water there, I quietly turned it back and didn't make a stink even though that had to be deliberate. She remarked that my fire pit caused some smoke to drift into their bedroom last year; I didn't burn it this at all this year to be kind. She was worried about some bushes on the lot line and I cut them far back the next day. She likes to remark that she chose several of the plantings in my yard for the prior owners and keeps track of them. I lost a dogwood in my front yard to an ice storm last year and she likes to comment about what WE should put in to replace it. Pretty nutty, very presumptuous.
And yet the first time I said no about something, she mounts her high horse. I realize I have let her run the show far too much in a misguided attempt to be neighborly and she is taking the proverbial mile. Perhaps she didn't mean to say my daughter shouldn't be allowed to move back to her hometown, but that was really the last straw.
Best to just let her be mad than to continually allow her to believe she is in charge of all she surveys. Band aid ripped off.
