Building on yesterday’s exercise, take some more time to consider your protagonist’s relationship with secrets and truth.
How does your protagonist react when someone gets close to a secret they’re keeping? Does he hide or get defensive? Does she go on the attack or make jokes about the topic?
The secret doesn’t have to be sinful or humiliating. It might be an emotion your protagonist doesn’t want to share or thoughts she doesn’t want to express. You’re here may not even be consciously aware of the problem, and could be avoiding or protecting something without realizing it.
