human things I think Vulcans would be good at:
getting a return processed at Target
birdwatching, but for like. algae and slugs and stuff. (they’re too advanced for just birds)
dealing with medical negligence
online shopping (they have 2k tabs open at all times)
marketplace bartering (in any locale)
elementary school riddles (green glass door, etc.)
starting underground rainbow loom empires (adult or child, doesn’t matter)
cutthroat pitchfork reviews
letterboxd (rating film by various, limited metrics? they consider it humanity’s greatest contribution in eons; one of the reasons they make first contact)
writing unhinged YouTube comments
patiently discovering, and reviewing, each ending of a choose-your-own-adventure book
