Early one spring morning during the pandemic, I was in the Queen’s private plane on the tarmac of Belfast International Airport watching Boris Johnson frantically searching for the No. 10 mask his team wanted him to wear. He was full of “Ahs!” and “Ohs?” and “I must have it here somewheres!”, as he emptied his pockets. Then, he found one. He pulled out one of those blue-and-white disposable masks that you are only supposed to wear once and then throw away. This one looked like it had been used before.
