It’s a bit shit isn’t it?
It looks like one of my siblings A is gearing up to cut the other B off completely. Tbh there will be some relief in not having to negotiate between them. I recognise the benefit of A waiting until both our parents are dead to do this too.
But it does have an impact. Incidentally I am not in touch with a former brother in law following a terminal row after being widowed of his brother. So I recognise that it sometimes happens. Still a bit shit.
