I don’t understand the holiday thing either. Seems utterly mad at this time to travel halfway across the country, spend hours in an airport and then in a plane with a mask on, and then sit on a beach with the same colour sand you’ll find at any number of UK destinations! People knew things might change - or they should have known. But, then again, the transport secretary went, too, so who knows.
Oddly, one thing this has made me think is that, when things are back to normal (and I’m sure they will be at some time next year), do the things you want to do, and see the places you want to see, because you never know what might happen!
