You will need two 15-minute segments of time to complete this exercise in "reading between the lines."
Select a historical or fictional book that you might consider to be rather dry reading material. Depending upon your tastes it could be the Holy Bible or Catcher in the Rye. Find a story about people, and read a paragraph or two carefully. Think about what was it like to be those people. What motivations could they have? What pressures were they under? What do they want and why are they doing what they're doing? Use your imagination to fill in the details of their lives that further explain and enlighten the story. Have someone ask you these questions about the story and hear what you come up with.
