I don't care, I think she should do what she likes with her money.
My parents were distraught.
The background is that my sister called my DS2 (SN) on his bday. I had tried to manage this and had coached him and called her - she was out. She called back and he had forgotten who she was - he never sees her. I was in the background grimacing and saying "be nice, she will give you presents" he then said "what are my presents?"
I then called her back immediately and said "sorry, it was just bad timing, DS is what he is, it isn't personal".
She flipped and went to our parents saying what a shit he was, etc, etc. Then she used the family website re-writing her will about 7 times - publically. Eventually I asked my Dad to ask her to please use her private email address.
I have never wanted, asked for or expected her money.
The tin hat was that she said, in her will, that she would leave mum's wedding ring (which mum outgrew 20 years ago) to DS1, not me or DS2. I have told DS1 never to accept it.
