This is clearly Meghan’s big thing. IMO, effectively, she’s been building to this all her life
I don't think she has though.
She's missed a good 5 years when she could have been building towards this. She could have used the Covid hiatus to get a social media persona set up, posted cooking videos, little 'sneak peaks' into her life and so on. Instead, she's used the time to indulge in bitterness towards her in laws and bizarre pseudo royal tours. So it's pretty hard to taker this 'positive vibes only' SoCal girl persona seriously.
She clearly thought she was way too good for this sort of thing now that she's a Duchess, and is just going back to it as a last resort. Right back to where she was 10 years ago, but the world has moved on.
