Nana8, if we ever get a chance to talk to her that might be a very helpful approach! Thanks. She has so far hurled odd accusations but not been able to clarify what the issues are, eg, after one of her noise 'complaints' (which involved her repeatedly slamming her front door, fracturing the rising main and sending emails telling us this was her revenge for our awful noise) we emailled and asked exactly what, where and when the offending noise was so we might be able to do something about it but so far she has never responded to things like that and refuses to discuss. We wondered if it was the communal door slamming (could be any of 9-10 upstairs residents coming and going plus post and delivery drivers who are buzzed into the hall) as it made no sense in terms of what we were doing (reading quietly in bed) but because we don't know what her problem is we can't do anything. It's very sad but also upsetting as it disturbs a seriously ill person who lives with us. We can't sell up now without declaring it to a buyer, so we may have to move and rent the flat out, just for some peace. Anyway, she's been quiet since we told her to stop harassing us a few days ago, so fingers crossed it lasts for a while.
I've got another 'keen'... Ouch!
