What was a bad choice Jem made in her life and why she now feels it was the wrong decision.

Because she knows the date of a person's death, Jem avoids looking people in the eye, a habit that prompts many to believe she has something to hide or is lying. Though she knows that a boy named Spider is going to die in a matter of days, Jem finds herself drawn to him and they become friends and then lovers. Jem struggles with the question of why she sees the numbers, whether they can be changed, and why anyone should try to make things better if everything is predestined.
