Does your everyday life seem pretty unglamorous? What about your town?
What if you walked down the street one morning and discovered that a whole bunch of glamorous, exciting people had come to town for a spell?
Write a story about a small town invaded by glamorous/exciting people
The exciting people could be movie or pop stars on a location shoot, or high-profile politicians in town for a rally, or scientists flocking to study an unnatural phenomenon (think: Flight Behavior by Barbara Kingsolver), just as long as it upsets the status quo.
Who are they? Why are they there? Who do they meet?
What do the local people think about all this?
What does your main character feel about them at the start of the story? At the end?
Who learns something from this visit? What?
Also, if you have only ever lived somewhere exciting, seeing celebrities at every coffee counter, write instead about someone really ordinary coming into a situation filled with glamour. Ask the same questions as above?
