I think she sat alone, to show an example, due to covid. Very wise...
I still can't give a monkeys about who partied and when. They gave the advice that was... potentially, safest, which was right. Risked themselves, up to them.
What bothers me is those fined or literally prevented from seeing dying people. But I see that as a different issue... that was down to lockdowns, which a lot of people did agree with. Any parties didn't affect that.
The biggest problem maybe, was too strict lockdowns, with no personal choice, but that probably wouldn't have been popular either.
