An adaptation of BJ Novak's "One More Thing: Stories and Other Stories"
It's a 16 page accordion (back to back), showing two connected short stories on each side. One side tells the story of a guy who wears a red shirt every day as a systematic way of meeting the right girl ("All You Have to Do"); while the other side tells the story of a girl looking for the guy she met who wore a very distinct red shirt at the store ("Missed Connection, Grocery Spill at 21st and 6th 230 p.m. on Wednesday”).
The stories of both characters intersect at the grocery store - and also (physically!) on the accordion where that specific scene is shown on both sides of the same page.
