Allie is back with another guide for girls, the theme this time being responsibility. Allie's parents have told her that she is not responsible enough to have a cell phone, and she is determined to prove them wrong. On the field trip, Allie comes face to face with the group of girls that she had trouble with in the last book, Glitter Girls and the Great Fake Out. These girls behave rudely, and not only does Allie stand up to them, she goes out of her way to defend another classmate who is being bullied and made fun of by other children. In spite of unkind behavior by Mary Kay, Allie rises above her past slights and befriends her in a time of need. Allie comes to realize that understanding the past, on both a historical level and on a personal level, helps you appreciate the present. Her faith in her quality friends is confirmed.
