I can't find a source right now, because I just woke up and I don't want to, so (Trust Me Bro, et al, 2024) but there's a chance that quote is actually about Nazis!
A lot of French people referred to them as "the others" and would often speak sort of semi-codedly about them in writing and such so as not to piss off their new overlords. So that line may well not have been "I'm such an introvert that being around other humans is like being in hell" but instead "hell has delivered itself to my doorstep in the form of goose-stepping bastards"
Your brain is a confusingly, terrifying, beautiful place and I'm glad you just give out front row access like this.
