Two days after the NYE ringers' party at which masks were optional and vast quantities of food were eaten. I think there were 4 or 5 of us masking, but some people were eating and then re-masking (I did not eat).
To be fair, I was on the packed Red line on the way home, with only a handful of maskers, so I can't really complain about the ringers.

I introduced "Bobcat-robots" to someone with whom I had been using "units per unit." b-r is more memorable.
