I have a relative who IMO makes assumptions about why people treat her as they do, or why things happen to her.
e.g. I hadn't told her some news about my adult son. Not for any specific reason, I just hadn't done so. There are lots of people I haven't told. It's his news anyway, though nothing I can't tell people.
So, it came up at the w/e and she expressed surprise she didn't know.
And then she went off on one about how maybe it was because she didn't deserve to know because she's just silly old Susan, who people don't care about and that she should just sit in the corner and be quiet.
This isn't the first time. I was challenging her about what she said, but she just went on and on until DS2 leaned over and told me to chill out.
I did just drop it because it's like she wants to play the victim and brings up stuff from her childhood. I only got to know her when I was an adult and she is the generation above.
I don't think this really thinks I think that of her. I honestly have not given her any reason to. It just pisses me off.
