As someone who spends equal amounts of time writing and reading stories, I often only get the pleasure of being surprised by the latter.
Usually, I see all the twists and turns coming in my own stories because, well, I'm the one doing the storytelling! Yet every once in a while, every so often, I find that I surprise even myself! I simply love it when my carefully crafted "plan" is shattered because one of my FICTIONAL CHARACTERS goes off the rails and does something totally unexpected all on their own!
