There is no reason to believe that anyone who's gone this long without getting vaccinated would not lie casually about being vaccinated to trash the mask.
One of the unanticipated perks of the mask has been that I didn't get a cold or the flu or another virus: I haven't been sick since the February before the shutdown.
So I think I'm carrying that mask into the future for public situations so I don't have to rely on the word of some real idiots. About any damned thing. After all, I have underwear more uncomfortable than the mask.
