The running theme in this movie is that she has big emotional outbursts, which she describes as going berserk. And I think it's just Wes Anderson's quirky casting, but they are also much older parents to relatively young children. We don't see a lot of what precipitated it or what happened after the fact. It seems like almost immediately after the situation. She mentioned something about picking the glass on her mom's hair. Even as I was already feeling really bad about what I'd done. So all this reminded me of a kind of explosive behavior sort of called Intermented Explosive Disorder (IED)
