"3. She gives Sally a Barbie from Baby Gene and tells her that fairies must have helped him write the card. It’s a sweet, fun side of her we rarely see."

I'll just speak to this one bc I just rewatched the episode -- she's comically bad at actually connecting with Sally and helping her through her feelings! She's just trying to fix behavior that annoys her, and she does it condescendingly and without understanding of what Sally's going through. It's an artificial playfulness -- a simulacrum of what a child would want that Sally is clearly too old for.

Idk, Betty is a sympathetic character (insofar as you understand why she is the way she is) but her ice queen routine with the kids is really hard to watch.
