I have not met them personally either. Just see them around London , going about my business and they come trotting by for an opening or some other function. I have seen the lot of them this way, over the years. Never on purpose and never by plan. Diana, in my view, was the only one who seemed to truely enjoy the limelight and she sure did shine in it.
Camilla, of course she likes the servants, the shopping [I suppose] and the other perks. She deserves it, after all, putting up with Charles all these years.
