Are there still such thing as vacation slides? Never mind. I’m old enough to remember. Have you ever had to look at the pictures from someone else’s vacation? The first few are enjoyable. The next batch becomes a struggle, and too many are very painful.
In flash fiction the writer can only show one scene, one picture to their audience. What if you only could show one picture of your vacation? Which one would you pick? The best one, of course. It’s the same for your flash fiction. Show the audience the best scene because it’s the best picture of your vacation/story, and the most enjoyable experience for them to read.
