We have an arsehole loud neighbour. At his worst in the summer he has socials in his back garden almost every night. For some reason we now hear him in house, which was never a thing before. The three hour phone call at top volume at 3am just after Christmas, while I had pneumonia was a low point. He takes a lot for Mr Ag to get annoyed by someone, but he's fully onside now.
We'd complained a few times, but it never dramatically improved.
He tried to talk to me over the fence about a month ago, just about the gardens (we normally have a decent enough relationship, we've had a drink together before). I pretended I didn't hear, as by that point I'd had enough. We then got a poorly written note through the letterbox, part grovelling, part accusatory. I never responded, and to my surprise, he does seem to have simmered down somewhat.
Oh yeah, he's 62.
