Clarisse McClellan walks with Montag on his trips home and is one month short of being a 17-year-old girl.[notes 3][20] She is an unusual sort of person in the bookless, hedonistic society: outgoing, naturally cheerful, unorthodox, and intuitive. She is unpopular among peers and disliked by teachers for asking "why" instead of "how" and focusing on nature rather than on technology. A few days after their first meeting, she disappears without any explanation; Mildred tells Montag (and Captain Beatty confirms) that Clarisse was hit by a speeding car and that her family left following her death. In the afterword of a later edition, Bradbury notes that the film adaptation changed the ending so that Clarisse (who, in the film, is now a 20-year-old school teacher who was fired for being unorthodox) was living with the exiles. Bradbury, far from being displeased by this, was so happy with the new ending that he wrote it into his later stage edition.
