I honestly have not drilled down into it with him. I live several states away. we aren't close relations. when I stay with my parents for like holidays in the same state, he doesn't come over for stuff because of his "allergy". he won't venture into their house (wifi). they exchange stuff in the driveway and visit briefly then.

the whole protocol is absurd and I don't participate. I would not keep a straight face.

no clue if they've gotten the covid jab, but it wouldn't surprise me if they're on the 5G train.
