I think for people who are dutiful and sensible, and I know a few, there will always come a time when they are accused of not emoting enough; not being real.
Well, Kate's sister-in-law has just been interviewed by the most famous host in the world giving her real truth. Kate and Will are left seeming like wooden dummies in tweeds and pastel dress coats by comparison. So I think Kate is having a bit of her own truth, going back in her mind to when she was single and spending time in London and doing what she would have done then.
And she looks sincere doing it. She looks like a slightly more dowdy version of her royal occasion self. And I think she does have a sincerity and conviction. It shows.
She does the royal job well, judges formal and personable and how to strike the balance. She looks a bit posh because she is. Her parents business did well and so they sent the kids to Marlborough School. She can't help that, any more than Harry can help being born royal. Kate knows that Will and Harry's friends probably think she's not from the top drawer and not as upper class as them, but she does what she can to be elegant and gracious and does everything she's asked.
Lots of people have met her and post things about her on forums like this, and nobody ever says she is unpleasant.
But personally, I think the formal roles suit her and also her husband better than informal pod casts, and I think they'd do well to stick to official types of celebrating ordinary citizens for their society-enhancing volunteering, rather than speaking out off the script sheet. They don't really have that sort of 'from the heart' connectivity - but, no worries as you need all types to make a world, and people do what they want to do for the better in all sorts of ways.
