@Rika-Chicchi Maybe

complained about

's Math/Science/History Lessons once too often?
Like that:

"...And that is how a so-called Lunar Eclipse works. Any questions left?"

(snores, yawns, boos, fart noise) "Booooriiiing! I want to go out and beat up some rogue Earth Thugs!"

"Me too!"

"All right, I quit. It is hopeless. But do not come up crawling back to me whining and with whip marks on thy ar**s again because thou failed another test and thy parents punished thee for it." *Packs her stuff and storms out, visibly p***ed*
Or would this be more to your Liking, as a contrast for the Modern World?

P. S.: Now with the Passing of 24+h and in Retrospect, wouldn't something like a
Terran Eclipse be more appropriate to learn about? I doubt one can actually properly watch a Lunar Eclipse if you're
living on the Moon.
