It can always be worse. I had the dubious experience of logging into an account at one of the schools I teach at to get started building a class I only teach in spring. This was in 2021, during the pandemic. There, in my online canvas files, was a shit load of video lecture that I had shot for the class under some degree of duress—as felt by many instructors worldwide—in SP2020. I had NO MEMORY WHATSOEVER of having shot all that footage, and yet there I was on video, in my home studio, with segment after segment, and lesson after lesson on file from the previous year.
Pretty fucking disconcerting, frankly. To be fair, there was other stuff going on in my life at the time that made the pandemic seem like an also-ran problem, in all, but yeah… memory can be tricky, and absolutely comes apart under stress.
On the upside, the person that I co-instructed the course with confessed to having had the same experience logging in to discover all these power points for her portion of the material from 2020–also with no memory at all of having built the slides.
Even better, since all that shit was still there, it was a lot less work to get the class up and running than I was expecting.
