Our flat is a house converted into two flats, upstairs and downstairs with a communal corridor and main front door.
We live downstairs and our neighbour upstairs is a 71 very eccentric (and sometimes quite difficult) lady.
She is very noisy, constantly banging around and moving furniture (that's what it sounds like anyway) and has several times accused us of things like hacking into her computer and tapping into her electricity supply!!! Anyway those things eventually culminated in a heated discussion where she proceeded to call me ignorant and uneducated but eventually she realised she was being unreasonable.
The latest thing is junk mail coming through the main front door, duplicated as its clear it is two flats.
We pick ours up as often as we can and dispose of it but don't pick the duplicated items up as clearly they are meant for her and so not our place to dispose of them.
They have been piling up (neatly and doesn't bother us) and this morning on my day off I heard her in the corridor shout "I shouldn't have to tell adults this but please remove the trash from the corridor" I then later looked in the corridor and she has moved the pile right in front of our private flat door!
AIBU that out of principal there is no way I want to dispose of that pile now, it won't make any extra work for me but I am shocked at her behaviour!
