Interesting, one has to wonder why at 50 something she was still in the parental home and why her siblings may have chosen to eject her. We'll never know the story, but I've seen similar ones play out and I can take a guess. Now she has 200K in the bank and no real anchor to the rest of the world and prima facie what seems to be some sort of personality disorder. Not sure what we do with that other than a hard-avoid in a self-protective capacity. Not your circus, not your monkey - cut and run as best you can.
I'm dubious about the wholesale lifting of the US racial experience here in the UK, I think it's problematic to assume our countries are culturally similar and have similar problems. We were electing mixed race MPs in the 1780s, have had a hindu Prime Minister and some of our most egregiously race discriminating politicians are themselves from ethnic minority groups - looking at you Sunak, Braverman, Patel and Badenoch. I tend to see entitlement in monetary forms - the main thing connecting those four people being their personal wealth being very high relative to the population.
The world has a racism problem - this woman has a massive racism problem, but I'm not sure the UK should lean too heavily into that as the answer to our political and social woes. :o)
