Yes - the Middies have been absolutely brilliant over many years. They've kept a low profile, not embarrassed anyone and they must have been a life-line for William at times, as well as Catherine.
Their (OK, very affluent) middle-class lifestyle and their more modest home(s) will have provided the Wales children with a much more normal and mainstream childhood than that of William, Harry, Charles and Diana.
I've read of some sad incidents, reported by Tom Bower who, while some people don't like him, is a savvy lawyer and doesn't risk being sued by including wild stories in his books. Apparentlyl, before the HAM wedding, the MIddletons made at least one (maybe more) overtures to Meghan to come and stay with them, and even invited Doria to stay on the eve of the wedding, but all invitations were turned down.
Now there might have been perfectly good reasons - we don't know - but I suspect Meghan wanted to keep her mother well away from them in the same way she wanted her isolated during the ceremony. She likes to be in control of what other people might talk about!
