My wife's church choir has a testing requirement: all members must test before taking off their masks before church. Not all people take the test; they say they do but they don't (it's called lying, and people do it in church all the time).
Four days later, a quarter of the choir has COVID.
Fortunately, she keeps her mask with her and puts it on whenever she isn't singing. And that is why neither of us has #COVID.
Wear a #mask, people. It's literally the least and most you can do.
