This short story first appeared in the Saturday Evening Post in 1920, and later became part of Flappers and Philosophers. Fitzgerald was the master of exposing the underbelly of the aristocracy and the pompous, and here, Horace the prodigy falls in love with Monica the dancer. Horace puts his lofty goals on hold to pursue a more lucrative career as an acrobat, while Monica writes a book.
The title "Head and Shoulders" doesn't make a lot of sense until you begin to listen to the story and find that Monica tells Harold they are like head and shoulders, he being the head and she the shoulders. That moniker sticks with them, although it is turned around at the end of the story. "But when you opened your door at the rap of life you let in many things."
