Oh this is a hard one. I will redefine to the story that has stayed with me the most - and I think that is A Jury of Her Peers, by Susan Glaspell https://twitter.com/PM_Jordan/status/1263716974946910208

But "When Robert and Crow Saved East St. Louis" by @Annaleen is up there, too. I love that story and think of it often. https://slate.com/technology/2018/12/annalee-newitz-short-story-when-robot-and-crow-saved-east-st-louis.html

If you want to read A Jury of Her Peers, you can find it online. But it is also the story that made me assemble Hemmed In: http://annorlundaenterprises.com/books/hemmed-in/

There are so many great short stories out there (not to mention the wonderful novelettes & novellas)! I want to share more I have loved and that have burrowed into my mind... but parental duties call me away from Twitter right now. I will come back and add to this thread later!
