It's not really apocalyptic fiction, more like a deep-thinking introvert trying to survive an anarchic environment after a catastrophe (not nuclear) that caused half of a town's residents to flee. Won't have any zombies, just alive man against alive man and alive man against nature. I want to make it as meaningful and non-cliche as possible, expressing themes of the advantages and disadvantages of introvert personalities as well as the good and bad of anarchy. How should I go on about writing the short story? What should I avoid, what sensory details should I use, etc.
