So, I became an limited expert in medieval weaponry, which didn't even serve me well in later D&D sessions because a "long sword is a sidearm damn it". Other kids became experts in dinosaurs.
How many kids would actually pursue learning about the phenomenon of "cafeteria services" and would that actually be something that was taught, that just seems ludicrous on the face of it.
Also, I have ADHD, the idea of pre-diagnosis me being dropped into this environment makes me wonder; would I have done better or far, far worse.
