Thanks, Jersey--agreed! I mean, he is on Paxlovid and much better, but still.

Doesn't help that my mom seemed judgmental of my getting Covid a couple years ago (at an indoor concert, where I knew I was taking a risk), as she was like, "We use hand sanitizer regularly and have been fine." So much of it seems random, like my dad got it from helping out a friend of theirs with back trouble. But they've also gone out to plenty of restaurants and stores unmasked. People who know they have it but are still going out contribute to the spread. (Same with flu or stomach bug.)
