That's very kind of you Reynard.
I've had a difficult relationship with him for many years, culminating in having to intervene when he attacked our daughter one afternoon 5 or 6 years ago (mainly verbally but some physical too). He had paranoid personality disorder which meant that almost anything anyone said or did had the chance of being misconstrued as a personal attack. He rang me up when our youngest got her first boyfriend (at 17 for goodness sake) and told me that she needed a boyfriend because she wasn't loved at home.
A stroke 4 years ago seemed to take all the malice out of him for a few years, but it's been sneaking back. Add to that an obsession with the medical profession trying (and eventually succeeding) in poisoning him and you can perhaps start to see why I don't give two hoots about his problems, other than for the damage it is doing to the people around him, his wife in particular. My wife has long seen him for what he is, and has helped her mum come to terms with all this. It was at her instigation that the Memory Clinic appointments led to this diagnosis. The net effect is that he can no longer drive, and all the official complaints he has lodged against various members of the medical profession can now be discarded. Other than that, everything just carries on as before, and all who have to come into contact with him carry on with their various coping strategies.
