My Zoom social happened after all. The other four participants had a lively discussion about the Barbie movie. I expressed surprise that they'd all risk another case of covid (they average about two acknowledged cases each between them) for a pop-culture movie.  

In the pushback and lively discussion that ensued, it became clear that they see Covid caution as a binary: they did (now they don't) take precautions. They never ask "is this particular event worth its specific set of risks?"
