I read that as the author, going to the funeral, broke down. That is they felt devastated emotionally, internally and possibly externally as in "broke down crying".
The funeral itself probably continued without any issues. I guess that's another social skills lesson, the world carries on regardless of your emotions.
3rd option is you just don't understand. This is language people use to describe narcissists. Flying monkeys are people who help them manipulate others and vampires are "emotional vampires". Poster was saying a narcissist had died, leaving their support people leaderless.
Is a lay ontology that's basically a folk offshoot of the proverbial 5th edition practitioner's manual and people use to keep the question of ethics in our closes relationships at arm's length (because they've also, like you and I, found this self-consistent set of just-so stories weirdly smeared atop all useful ethics and psychology discourse on the Internet) proto-AI spam or the reins of as many future mass psychoses as the doctor ordered? And are we cool yet?
Weird fantasies are fun and all until the world demands that you fit them into a pre-configured narrative a la whoever and then you lose the ability to have them.
It's an extremely uncalibrated reply given the context regardless, even more so expecting the general audience here to understand this weirdly specific language. Something is definitely off.
Sure. Way I see it, unless just epically pissed (many such cases), one would probably have to be epically pissed with the dead person and the people who came to the funeral. What I described is one schema for that.
What does breaking down mean to you? I thought they meant they broke down crying because they were sad. Not angry. Did you read it as that they destroyed something at the funeral?
