Yeah, I really wonder about that....whether even Charles and Anne were with her when she passed. Perhaps Anne was actually onsite at Balmoral....she seemed to be close to her Mother. And so I believe that certainly Anne may have been with her, or with her immediately after her passing. I think I read that Charles and Camilla were staying very nearby at another royal estate. Word went out over there around lunchtime (U.K. time) about the "concern" for her health....and I believe that by then she had passed. I really think that it was then about getting the rest of the children and certainly William there before the announcement was made. I believe those 6-7 hours were kind of a necessary thing for residents of the U.K. and really the world to prepare and kind of come to terms with the idea that the Queen had died. I know that as soon as I saw the news that I searched for and found several U.K. news outlets that were streaming live on Twitter that I could watch and listen to as I went about my day....because I guess I'm a bit of history buff and wanted to hear the news as it unfolded.
But I do think it's entirely possible that she died in her sleep from a catastrophic health event. We spent the day with my FIL yesterday to celebrate his 91st birthday. He's in great shape...still plays golf and everything. But he told us that every morning when he wakes up...that he's pleasantly surprised, but also that he prays that when he passes, that he just goes in his sleep. So, for the Queen's sake, and for that of her family....I hope that's how she went.
