The Book of Sand. Not fucked up, just mind-blowing.

The Bet, by Anton Chekov. That story has given me my existentialism

Top of mind for this subject: Flowers for Algernon.

Of Mice and Men might qualify, but weighs in at 100 pages. I'm not sure what the threshold is for "short."

On my own time in High-school, I read: I Have no Mouth and I Must Scream.

Blood Music absolutely terrified me as a freshman in high school

I remember "To Build a Fire" and another one I can't name about a sniper duel during the Irish Civil War. The ending was wild.

Edit: Was literally called The Sniper feel kinda dumb about that.

I don’t remember the name of the short story, but I remember that it was about a town that abused someone they kept in a dungeon, and through their abuse they stayed unified. The teacher said it was a lesson in utilitarianism.

I was a senior in high school when we read the short story "Rape Fantasies" by Margaret Atwood out loud in class. I was 18 and still not ready for it.

There Will Come Soft Rains

Someone already said it, but The Ones Who Walk Away From Omelas

Nobody else for Equus?

The Chaser by John Collier… that ending … still gives me chills

Harrison Bergeron, in like 7th grade

An Occurrence at Owl Creek Bridge by Ambrose Bierce. Someone did a great adaptation to film as well.

The one that sticks out for me is On The Sidewalk Bleeding. Wasn't even the most effed up thing we read in 9th grade, just had the most memorable name.

i figured the tweet was about The Lotterry and everyone would go "Oh it's obviously a tweet about The Lottery" but nope.
