Anyone else disappointed not to hear more about the Sheila interaction?
There is a lot of poison here, and I don’t think it is in Sheila.
I am sure these sort of confessionals used to come across as audacious. Now, it's just a tired trope of the format.
fwiw - I also wanted to know what happened there right after their encounter.
The "now" is especially important. It implies the friendship they shared was never real. Sheila was just keeping her around while she waited for someone better to be friends with.
I bet it's intentional.
