I understand your distress at not being able to visit your loved ones, your mother, father, grandmother or grandfather in their care homes. Especially now when you only want one thing: to hold their hand and comfort them.
I'm an American so I fundamentally don't understand monarchy. Rejecting that concept is, like, our entire deal. From afar, though, it looks like monarchs in Western society become the sort of care-taker of something important in everyday life: both pride in country and culture, but also some kind of model of the ideal citizen. I don't know, again, that role is so foreign to me (literally – hahah) that I can't analyze it. I think US presidents and celebrities fill this role for Americans, which has mixed results.
