From high middle-high school timeframe, probably The Yellow Wallpaper, I just think about that one at least a few times a year. And I only read it the one time in school.
The less well known one I remember from elementary school was My Brother Sam is Dead. It’s about a family during the American revolution, where the father just wants to stay out of all of it and live their lives, but the eldest son wants to join the revolution. The whole story is just the hardships the family has to go through after the son runs off with the only gun to fight and ends up dying, and how that affects the family and the youngest brother, who the story is told from the perspective of.
None of my friends remember My Brother Sam is Dead, but if I’m remembering right, the ending is kinda dark for a bunch of 3-5th graders.
Fun fact: The Navy uses the affirmative “aye” or “aye aye” as opposed to “roger” like the Army/Air Force/etc because of similar slang origins. Basically, sailors used to use the word “roger” to mean “fuck,” both as an insult and as a way to identify women they had been with while in port.
“Yeah, I rogered her last night at the tavern,” kind of thing. But as sailors began to respond to officers using “Roger that (fuck that),” the Navy came down and made “aye aye” the official affirmative response for their personnel.
And even then, “aye” is simply a “I understand” whereas “aye aye,” means “I understand and will carry out X.”
The US Navy also launched an investigative unit during the 1800s (I wanna say the 1880s?) to find homosexual sailors and kick them out of the Navy. The unit only lasted a couple of years before being shut down, as the only people volunteering for the unit were homosexual sailors. 😆
