How very sad. If you are in a small block and this lady has been there for years, do you not know this woman? Has she family perhaps you can speak to about her behaviour? Who told you she has dementia? I would like to think in the same situation as you I would try to get some help for her first and foremost. When did we stop caring about our neighbours? I get that she will be a burden on a Committee and should not be in that position. I get that it probably isn’t your problem. But really, stare down that future barrel, who might you be when you are old?
