I think it's unhealthy for us mere mortals to try to compare ourselves to the 1 in a million beauty, poise, grace and figure of the Duchess.
We'll never be in the same league, we just weren't born that way.
Well some of ye could be working catwalk models, but the vast majority of us are not.
She seems to be very much an involved Mum. A devoted wife, and goes about her royal duties with good grace and a beaming smile.
I'm sure there are many downsides to her life, but as far as I can see, she's a glass half full kinda woman - so all in all I'd say she is happy.
She has a lovely husband, 3 beautiful children, her family are all healthy - her own Mum & Dad are still young enough to enjoy their grandchildren. Loads of extended family. No health issues. No financial issues.
The price she has to pay is us lot commenting on her weight and her wrinkles and the size of her waist etc. I presume, as she seems to be of strong character, that she doesn't read any twaddle on here or elsewhere.
