It has long surprised me how many nominally-literate people struggle with practical reading comprehension, and yet it's true: a lot of nominally-literate people struggle with practical reading comprehension. And the more frustrated or upset they become, the worse their reading-comp gets. I used to be ???? that parts of my then-job were literally just reading to people what was freely available for them to read themselves, but eventually I learned to just shrug and read it to them, if that's what it took to get things done.
