Dig deep enough into most things and you’ll find a story, and when you’re applying that concept to your writing, you don’t even necessarily need to stop at people. Look out the window the next time you’re driving somewhere, you when you step out from a shop onto the street. Fixate on an object – something that grabs your attention. How did it get there? What was happening to it the day before? If it’s in disrepair, how was it broken? What memories are attached to it?
Sometimes, discarded objects create interesting vignettes.
