Had an ongoing problem with a woman last year, basically an ex of a then-neighbour. She’d stand outside his flat for hours on end screaming at the top of her voice. Let it go for ages because she clearly had issues and he was a nice lad and didn’t want to get him in any mither. One weekend she basically camped outside his flat and spent a solid 48 hours screaming, lots of it threatening, disgusting bile. After not getting an hour’s sleep on the Sunday night i phoned the police in the early hours, more for the sake of the elderly neighbours and families nearby, they came and duly nicked her, then knocked on my fucking door with her sat in the van right outside. Really appreciated that. Fortunately the consequences weren’t all that severe, but absolutely docile bastards. Next time i won’t bother.
