I wonder how I would have reacted 40 years ago if I could have heard a radio broadcast from 2022. There would have been the shock of learning about the pandemic, of course, but there's a smaller matter that would have puzzled me. If I heard a radio announcer giving a list of school closings, I would have wondered what a "remote learning day" means. I probably would have thought, "Does that mean the school expects everyone to gather in a different remote building? That doesn't make sense. The purpose of a snow day is to keep people from going out during hazardous weather. Or, will students be expected to work on some remote project by themselves for the day, such as reading part of a book at home that interests them?"
Without any context, I wonder what my final guess on that definition would have been in pre-Internet times.
