The title "A Day We'll Never Forget" is an appropriate title for the chapter because it describes the events of September 11th, 2001 when terrorists attacked the World Trade Centers, the Pentagon, and crashed a plane in Pennsylvania. The chapter focuses on Lisa watching the attacks unfold on television and learning that her husband Todd was on the plane that crashed in Pennsylvania. While the day's events were tragic for the entire country, the chapter emphasizes how Lisa will personally never forget that day because of losing her husband.
