Here Beth faces a tension common among teenagers: she is starting to gain greater independence (and in Beth’s case, considerably more independence than most). And yet, at the same time, she isn’t fully in control of her life—she still relies on Mrs. Wheatley to travel with her and dreams of her future as a professional woman, implying that she’s not quite there yet. This builds on the book’s portrayal of coming of age as gaining agency over one’s own life. At the same time, the book hints that, now that Beth is no longer a little kid, she’ll have to develop her talent in new ways.
