Kate Chopin’s “Story of an Hour,” Ray Bradbury’s “There will come soft rains” “all summer in a day,” and “the very gentle murders.”
Gilman’s “The yellow wallpaper” is a classic for a reason.
“The Lottery” by Shirley Jackson is jaw-droppingly gripping for basically anyone who is familiar with the Hunger Games.
“A good man is hard to find” is gorgeous and perfect and creepy (frankly, you can’t go wrong with any of Flannery O'Connor).
“Tell Tale Heart” by Poe is his best, and more accessible short story (“The Black Cat” is nice as well, plus the old staple “Cask of Amontillado.” “Fall of the House of Usher” is good too, and you could pair it with Bradbury’s “Usher II” with interesting results.
Oh! “The Gift of the Magi!” Anything O Henry! “A rose for Emily!” “thank you mam” by Langston Hughes. And so forth!
