I bought my flat a couple of months ago and it had been sitting vacant a while before I moved it. I can only assume that the occupant of the downstairs flat below got very used to this, and as far as I can tell has some kind of untreated anger management problem.
I'm a sole occupant, hardly ever even at home as I work full-time with a long commute, and as a serial flat-dweller I really don't produce much noise at all, especially at unsociable hours. However my downstairs neighbour seems to have a vendetta against me on the basis that I live above him. He recently started ringing my doorbell to punish me for, as far as I can tell, being on work calls on WFH days, so I'm at a bit of a loss in terms of modifying my own behaviour to appease him. The irony is that he is very blatantly the most inconsiderate and CF person in the building, having claimed swathes of communal space as his own territory. He also snores so loudly that it keeps me awake (and I'm not a fussy or light sleeper). I haven't said anything about this, even though it has made my life a misery.
I know it sounds quite minor, and quite far from "nightmare neighbour" territory at this stage. I'll admit to being on a hair trigger as I am recently out of an abusive relationship and have also been attacked by male strangers in the recent past. On top of having a stressful and demanding job, it just feels a bit nightmarish to not even feel at ease in my own home.
Do you think he'll get used to it and calm down a bit? I'd love to hear nightmare neighbour horror stories and hear what others did!
