One last attempt to explain loud enough to get through the fingers in your ears and the shouts of LALALA.
Saying "I'm leaving" is not the same as actually leaving. If your family are foolish enough to spend Xmas with you, when they get bored of your fascist ranting and say "we're leaving" that doesn't mean they've left. They are still in your house, still drinking the wine you've made from the bitter grapes you grow. They still have to follow your rules about using coasters and not dropping crumbs. They still have to listen to your unicorn grooming tips. They are about to leave, of course. Their leaving is an inevitability. But they haven't left yet.
And that's where the UK is. Still at the party, complaining about how much the tickets cost and how terrible the house rules are, while still eating and drinking as they have for years. Still convinced that once they actually leave they'll be able to make their own party that will be so much better and cheaper. Still dreaming of unicorns and sunlit uplands. Still very much at the party.
And you will be until the end of the year. Assuming Boris doesn't come to his senses and ask for an extension.
The ticking and tocking continues dribbles. My money is still on you and your type blaming the subsequent disasters on Covid 19. But who knows, maybe you'll surprise me with some personal growth that leads you to actually taking responsibility for the shitshow. But I doubt it.
