Every time I read something like this, it's a wave of sadness and empathy, then it's a wave of anger. I'm a generation older than the author, and went through a similar experience with my mother. I witnessed my cousin be thrown against the drywall so hard, he broke it. I'm convinced he has permanent brain damage today due to the abuse he suffered.
I learned from my uncle recently that my aunt and my mother were the product of horrendous and similar abuse from my grandmother. My grandmother, who my mother made out to be a saint.
Every fucking generation, this filial piety bullshit repeats itself.
