I have a nightmare neighbour. She lives on top of me in our block of flats. These are flats with outdoor space and we have a large deck that we can walk out onto. Her flat is partially above me and her deck is fully above me, although there is a large area of roof around her deck.
She is a bit odd and when I moved in a decade ago, she screamed at me in a mad kind of way for something I couldn't understand, so since then I have always kept my head down and avoided engaging with her. I genuinely do not know what I could have done to upset her, but she has taken against me (and lots of other people in our block too.) A few years ago I had a leak into one of my ceilings and the managing agents had to deal with her and it was a nightmare. She denied them access and made a fuss, swore and shouted at them and was generally very unpleasant and they had to invoke legal threats so that she would give access to the roofer. The leak was partly her fault because she puts a whole load of stuff on the fabric of the roof (i.e. the drain gulley) and it caused small tears and rain water started getting in. She was told by the managing agents that she couldn't do this anymore after they completed the re-roofing and of course she did exactly the opposite and it has happened again in a different area.
She is clearly livid that the managing agents need to have access to the roof and re-roof again and is doing all she can to be painful towards me. So she is endlessly spraying her hose over the edge of her deck so that water pours onto our deck below. She jet sprays the roof over the edge of her deck so that again debris and water flies all over our deck. Last week she stepped out onto the roof area and sprayed all the clothes on my washing line with something nasty. She also throws bread and and her plant pruning material down onto the deck. Generally, she is trying to spoil our use of our deck.
I don't want to raise a formal complaint, because if I do, I have to declare that when I sell up, which I want to do within the next 18 months. Also, even if I do raise a formal complaint, I don't think anyone can stop her from doing what she is doing.
I'm trying really hard to be the bigger person and think what a tragic, sad, bitter and twisted individual she must be, but it is testing my patience sorely. Other than taking deep breaths and counting my blessings - does anyone have any cunning suggestions?!
