Stiff-Upper-Lipism, aka "keep calm and carry on."
That Brexit was a hideous blunder must never be admitted and become news. Those who even whisper such a notion should be beheaded in the public square and/or have their tongues cut out as in the days of real manly kinglike Kings such as Henry VIII. I believe every Brit knows it but no one dares say it. Better to gossip about Queen Camilla or Meghan Markle and not hear "we told you so" from the rest of the so-called "free world."
Push all that under the carpet, keep calm and carry on and tell yourself it will all work out.. somehow. And then you can focus on much more important and exhiting issues such as celebrating the coronation of the Tampon King and his Whore.
