She'll be so pleased next time I take her task for choosing the slippery slide of "decency" and drifting into some version of, "well what did you do to him to make him think it was okay to do that to you? You must have done something, otherwise you would have been treated decently." This would have been followed up with a statement of how NO ONE would EVER do [incident in question] for no reason, like,

"Your brother WOULD NOT put Sparky (my cat) into the freezer for no reason."

"Your brother would NOT push you out of a 30 foot tree. His job is to look out for you."

"Your brother WOULD NOT deliberately put tacks all over the floor. You're lying. That was an accident. "

"Why would that boy do that to you if you were just standing there? You encouraged him somehow. Nobody would just do that. You better not say a word to your father. He'd be so disappointed in you."

I learned about Patriarchy from my mother. She's still obsessed with decency. Goes on and on about it all the time in between whining about how somebody did her wrong and how she didn't deserve it. Because she's just trying to be a good person and if everybody else would just "do right" (that's her phrase) she wouldn't be so put upon. Then there's usually a long suffering sigh.

(Maternal) martyrdom is so much work. No appreciation whatsoever for all the sacrifices, cause I'm an ungrateful brat, don't you know.

So, I can unequivocally state that she will be THRILLED to have your pity.
