nights of nothing

The assumer will see a social media post about someone's mushroom harvest, which clearly only contains exactly two distinct kinds of mushrooms, which the poster has identified and correctly named in the post itself, and the assumer will feel compelled to warn the forager to be careful out there! Some mushrooms are poisonous and they should be very careful to only pick ones they can identify! The assumer, who has ignored the fact that the poster did identify both of the mushroom species they had picked, and can most likely be trusted to do so in the future as well, has naturally assumed that the person showing off the results of their latest mushroom haul must have been obliviously picking them at random like an unsupervised toddler who is lucky to be alive.

If someone makes a post talking about how they just got a new job as a bus driver, the assumer might swoop in to warn them that driving a bus is extremely dangerous! It's so dangerous that it's literally illegal to do that unless you have a specific special training for doing that! Even a normal driver's license isn't good enough, you need a special license for it! And when the person who just got hired as a bus driver verifies that yes, they know that, they do have the license to drive a bus, and that they wouldn't have even hired someone who doesn't. The first question of the job interview was about making sure that they have a valid license for driving this type of vehicle.
