People like to make out her life was easy and that it's not fair that she inherited such a privileged position, but I think the exact opposite. Her life seemed like living hell to me. Every day for the last 70 years she's had to serve this largely ungrateful country, and she did so without complaint. Even in her 90s she took her duties extremely seriously, and I respect the hell out of her for that.
It was only a couple of days ago she invited our new PM to Balmoral Castle to form a government. She was clearly looking weak and it's been no secret that she's been struggling to fulfil her duties as Queen for a while, but even just two days before her death at the age of 96 she put on the performance that was expected of her. And she did this practically every day of her life.
RIP. I doubt anyone will ever live up to her legacy. Despite all the problems I have with the royal family, I couldn't feel more pride that she was our Queen.
This doesn't really address why anyone is "ungrateful"...
Btw, whilst Hong Kong has fallen and hence I do not expect much there the Hong Kong people like her very much. Called her the “Bossy Granny” and even with a sony on 1997 naming her as the righteous friend that help Hong Kong to trade well by being on the coin, always young and bring prosperity.
Miss her we will. God bless the Queen. RIP.
