Yeah, you can imagine it being pretty impressionable stuff for a 10 year old.
From a constitutional point of view, too, abdication just isn't the done thing here, whereas in the Netherlands in the 20th century at least, it's fairly commonplace; Beatrix inherited when her mother abdicated and her mother inherited when her mother abdicated. It's just the done thing.
Maybe it is better to change monarchs more often now they're all pretty much guaranteed to live a long time, but I like Queenie, and given its practically a ceremonial position, does it really matter how old she is?
