So here's how it went:
I noticed that wifeNeighbor (WN) had some clothes out to dry, so I camped out on my deck (next to their driveway/ back porch) knowing that she'd come out at some point to get the clothes. I busied myself with yard work (what else), sweeping up fallen trumpet vine flowers, etc. I was inspecting the lilac and noticed that one whole branch from base to end is dead, and that gave me an idea. Went over to their house and knocked -- nobody home. Phooey.
Went back to my tidying.
About 10 minutes later, they drove up. They had to pass close by to get from car to house. I said "Hi there!" brightly and waved. HN (husband) waved back in a friendly way, WN waved a bit and set her sights on the door. I called out, "Hey guys, I have a question... This branch is dead but a lot of it is on your side, do you have any problem with me cutting it down?"
(See what I did there?)
I didn't direct it at either of them but was looking mostly at WN, they both came over and took a look, sure no problem. As WN started to move to go back in, I gestured to the mulch (that's where it was), and said, "Gosh, thanks so much." She laughed a little uncomfortably. With a little smile and light tone I said, "So, what else did you do in the front yard?" She said "Nothing," in a kind of clipped way. I said, "Oh, really?" pleasantly. She said, "Well, I did some weeding." I said, "Thanks, it looks like you did a lot of work, I appreciate it. It looked like you cut back some of the vinca, too?" She started to say no, then said, "Well, a little by the elm." I was nodding/ appreciative throughout this part. I furrowed my brow a bit and said "Oh, so you didn't cut back around the snapdragons?" She said "no" quickly and then "Oh, well, the vinca was choking them off." I said with a smile, "Well, they
are annuals..." She said, "I won't do it again," made a half-goodbye/ half-talk-to-the-hand gesture, and went inside.
Hmmm.
I still hadn't finished tidying and so continued to do so. About five minutes later she came out with a very emotional expression (tight, twitchy, not so far from tears) and said, "[sozobe], you have to do something about your back yard. You have to get the poison ivy away from my fence." I said, "I know, I feel terrible about the back yard, it looks awful..." She said "Yes, it does," and looked towards it with a stricken expression. (There was more of that that I don't remember -- me being apologetic, her reiterating that it was simply horrendous, but I don't remember how it went exactly.) Then I said, "I was so gung-ho at the beginning of the year but that poison ivy really threw me for a loop..." [no reaction] "...anyway I agree something must be done, we plan to do something tomorrow, so we'll be sure to get the poison ivy by the fence then." (More reiteration of "awful" from her amidst high emotional expressions.) Me again: "I do feel badly about it, it's hard to know where to start but I have to just attack it. Frankly, I find that poison ivy terrifying!" At that point she just kind of nodded and then turned her back and left again.
(While I used quotes, none of this is exact [though I tried to make it as exact as I could] -- happened about 3 hours ago and some exactness has faded.)
Second part of the story is that E.G. was also doing some yard tidying, had brought a fallen branch to the curb just as HN came up with the dog, at the end of his walk. THEY had a talk, too. We'd had the sprinkler on and just then it started to rain; E.G. said, "Good thing we've been watering." (As in, irony.) HN chuckled. E.G. said, "So, we're gonna get to that backyard tomorrow -- guess that'll be good, huh?" HN said "yep," kind of non-commitally. E.G. started to apologize and HN stopped him with stuff about how he understands that we've been busy, that the poison ivy is intimidating and makes it a huge job, that it's not that bad anyway (really isn't!!! despite my make-nice apologizing to WN), to not worry about it, no big deal. Nice neighborly stuff.
I'm feeling pretty good about it. I think I handled myself very well, and I think things have been set up for a cordial but not bosom-buddy relationship, especially after we get to the back yard tomorrow. It allows me to do something in good faith that is concrete, not the guess work about "how can I make her like me??" -- if she still has a problem with me after I do that, that's her problem and ever-further into irrationality. Because that was the other thing that was satisfying about it -- it took all of these suspicions I had and made them concrete. Her emotion and anger were just WAY out of proportion to the reality.
By the way, here's my back yard a couple of months ago. The grassy patch is weedier and browner, but otherwise it gives you a pretty good idea of what is going on.
And more to the point (I think) it is really not that different now from what it looked like when we moved in a year ago. At that point it had a lot less grass, a lot less
green grass (the shade-tolerant grass seed I put down seems to be doing better than the stuff that was here) more bare dirt, less weeds (though still a lot of weeds), and a lot more dog poop. And the mother of all poison ivy vines is many, many decades old, so it's not like that's our fault.
Anyway, I'm feeling good about it overall.
Thanks again for all of your insight, advice, and support, has helped enormously.
