My 30 year old sister in law throws disregulated tantrums somewhat similar to a 3 year old. She failed out of college before completing the first semester, went to a bougie AA retreat in Hawaii for many months, made her entire identity AA, until online outrage became mainstream. She might literally have never read a single book cover to cover in her life, and yet has the strongest polarizing opinion you could imagine on every complex topic. She’s basically a sentient Reddit thread.
It’s sad, but also unbearable to be in her presence. The way she screams at her parents is so embarrassing. I feel bad for her parents, but they also coddled her to death and continue to to this day.
