...yes (re council tax). There's no getting through, they believe it's their space, that it's essential for any visitors to park right outside their house (have never said why - if there was a reason i might be sympathetic) and frequently mark it with cones (often a day in advance of any visit, likewise with the chasing and shouting). Actually it's easier when they do, as at least i know they want it, than when they don't, then shout or knock.
So, she asked me to move closer to our house. I pointed out that I was as close as I could get (I was). She asked me to move the car as soon as a closer space became available. I said I wasn't playing that game as I had better things to do (some neighbours do, to move outside their own houses). She expressed outrage that once, our car had been outside their house for two days!! I said she was being unreasonable (yes, I actually did), she said 'no! it's you!'.
It's tricky actually because they are neighbours, oldish and I'd rather get on nicely. I just wish they'd asked nicely, just once. We do have a reciprocal 'no parking' arrangement with the NDNs because though DP in particular thinks its all nonsense, they asked, they're our neighbours and it clearly matters to them. Unfortunately the 'unreasonable' couple's only communication with me has been demanding, impatient and critical. There's underlying pleasantness and manners which sometimes show through but usually, by the time he arrives on the doorstep he's in a state of outrage, so starts by being accusatory and demanding.
I'd like to be nice but do think it's all nonsense (and have a belligerent streak). DP pointed out that an assumption that the neighbour might be responsive to rational discussion was not a safe one. I sometimes don't think of that. I suppose someone who shoves bits of railway sleeper under cars might not be...
