As a victim of the US public School system, every class had one or more kids that simply couldn't read aloud in class for one reason or another. The teachers learned to not call on them in the future to keep things moving.
Some of them got moved to special education classes over the years, but in my experience they were just free periods to keep them from slowing the other kids down.
It's sad, I knew a guy that was smart as a whip, but we went to a restaurant he wasn't used to and he sheepishly asked me what was on the menu since there weren't any pictures.
I have 'Agenbite Inwit' tattooed on my person and feel as though this ogre meme has called me out.
