I don't have to say which queen. I'm tempted to say, very unoriginally, that her death is the the end of an era. But it really isn't. The era had already ended, and she was one of the last remnants of it. Removing most of the power from the monarchy had the effect of emphasizing its value as the symbol of an ideal, and she was a worthy representative.
As someone said elsewhere, she knew what it meant to do one's duty, no matter what. That's not much understood now, though I think, or hope, that when it is understood it's still admired.
Most deaths are personal. They involve the deceased and those who knew him or her. Even when it's a public figure, most of us generally note it with only mild interest, perhaps wonder in some cases how it will affect this or that thing in which the person was involved. Politician: who will succeed him or her? Artist: either "well, his best work was in the past" or "there might have been great work yet to come." Rarely do we feel that the whole world has somehow changed. I felt a bit that way when Johnny Cash died, not because he was such an important artist but because he had always somehow been a significant part of the world, and that the world was changed by his absence. I feel much more that way about Elizabeth's passing, because she represents much more.
