What is the plot of a day's wait by Ernest Hemingway?

A Day's Wait describes a miscommunication between a father and his son and the tragedy it brings. The story begins with a little boy who is sick with the flu in the winter. The doctor tells the father that his temperature is 102 degrees Fahrenheit. The boy starts to tell his father how he will die because in France 102 degrees is lethal. His father explains that in France they use Celsius, so the boy will be fine.
