Those who were interested or pro the monarchy, joined the celebration even if it was only watching on TV. Those who weren’t interested didn’t do celebratory things, although lots of them watched it, either at the time or in the news so they knew what to complain about.
One Oz friend said she wouldn’t be watching, then posted regularly about throughout the day on FB and evidently toasted the king with fizz.
I’m glad some posters finally found time to do their gardens or polish the silver thanks to the Coronation rather than drinking from early on in the day.
I’ll be using the Eurovision events for a similar purpose, but without the drink.
