This quote is so very important to the plot of the story. Not only are words a powerful tool to be used in any society, Liesel gained many of her most important relationships through words. She bonded with Papa over him teaching her how to read (and roll cigarettes), and he became one of her very best friends. She gained another friend in Max over books, reading, and words. Words mean everything to Liesel, and she shares that love with Max, who lives for his friendship with her.
