I had a gf in college whose best friend was complaining about her boyfriend getting "obsessed" with some "psychology self help guy". I asked if it was Jordan Peterson, she said she didn't know, then I asked if he had the 12 rules for life book, and she said that was the one!

Afterwards I told my gf "they're gonna break up within 3 months". I was wrong. It was only 2 😌
