Little pet peeve of mine... I mean, it's great if a writer can truly adapt a story, twist it's events, or pluck a character straight out of another's world - but fanfiction that literally copies the plot of another work, almost word-for-word, somehow makes me sad - y'all have worlds bursting with stories, dreams to be heard, and chosing to repeat some else's story takes away time to share your own.
Please, don't just rephrase some else's work in fanfiction. Make it your own.
