Why do Zeus and Hera hate on Amphitrite so much? She seems like she's living her best life?? Also, I get the following vibes from the three of them: Zeus - beer dad, Hera - wine mom, Amphitrite - vodka aunt. Thoughts?

Those are 100% valid vibes.

And I think they hate on Amphitrite because they themselves are unhappy. Amphitrite found a way to give zero fucks about what anyone thinks of her, and still have a happy marriage with Poseidon who enjoys fucking anything that moves.

Zeus and Hera don’t want to share their spouse with anyone else. But since Zeus doesn’t care what Hera thinks and philanders to no end, and Hera is not only a female enforcer of the patriarchy but someone who want to be with Zeus and only Zeus.

I can see how someone like Amphitrite would stick in their craw.
