I remember every moment of Diana and Charles' engagement and wedding; I was 13 at the time and thought it was the most romantic thing I had ever seen real-life people do. I still have a mug from their engagement, with their two faces on it. LOL!
While I haven't been following this story avidly, I think they are a good match and have been together for so long they will likely avoid all the pitfalls of public life that his parents and his uncle and Fergie fell into. I'll be watching for the fashion, for sure; Kate is always dressed impeccably!
Giving her Diana's ring is sweet and sad at the same time. Whenever either of her sons mentions Diana, it brings home instantly that while she was such a mythical public creature to most of us, to those two boys she was and is just their mum. What a lovely homage to HIS relationship with Diana, which is what is important.
