Good Friends is a short story by R. L. Stine that appeared in the author's first short story collection: "Tales To Give You Goosebumps: 10 Spooky Short Stories." It's about three friends, Dylan, Jordan, and Ashley. Ashley has an imaginary friend named Jaclyn who plays dangerous pranks. Dylan, Jordan, and Ashley plan to destroy Jaclyn, but in a Goosebumps-esque twist at the end, it's revealed that Dylan's two friends—Jordan and Ashley—are imaginary.
