This is just one of the places this could go:

Meghan is an American and not a part of the blood royal: But she has married into it and her kids are a part of it in some context. So where is her royal privilege? In other words, it is part of human nature to exploit an advantage, and the concept of 'unfair advantage' changes with one's, er, vantage.

Just sayin'...

Another place this could go:

Meghan said, if I understood correctly, that she did not get the most basic of instruction in behaviour. As in, "you know how to curtsy, right?" Well she did not know how to curtsy. This apparently happened when she and Harry were dating, so it comes off as delightfully impromptu as narrated. But then she actually is married into the family and all at once she needs to be educated on a lot of ceremony and formal behaviourisms. She claims she got no help on this. So we're beyond impromptu at this point. I'd guess there is as much detail and history on this sort of thing that one can get sucked into a rabbit hole in no time. So she needed someone who could figure out what actually mattered and also what would matter most to Meghan. That is a tall order which apparently didn't get filled. And it is different but related to the depth of press coverage and that added coverage of tabloid sensationalism and stuff-made-up-ism.
