We self-critical British should never forget that other nations are pretty crazy too. I write this from Andalusia, Spain; and when it comes to cockeyed rules for limiting the spread of Covid-19, the Spanish offer us some stiff competition. One is reminded of the Mad Hatter’s Tea Party. Very gradually (I’d guess) over the months during which Spaniards have been subject to a face-mask regime, people seem to have lost touch with the reasons the rules were laid down in the first place.
