As annoying as that question is, I want you to think about it now.
Now take that memory, maybe dress it up a little bit, and put it into a story. Not as a memory, but as action in the story.
Ulterior motiveFinding inspiration for a story is often a problem. (That's kind of the reason I even put these writing prompts together.) You probably have more in your past to work with than you thought.
I hope this exercise takes you down memory lane a little bit. Recognize that any of those little memories you think about as you burrow into your past could be the core around which a story can be built.
