How does Heather mature by observing Robert's immaturity in the novel, Wild Robert?

As Heather comes to realize that Robert irresponsibly uses his magic arts because he never really grew up, she develops greater maturity herself. The pity she first felt for Robert grows into an improved understanding, and a genuinely concerned approach to others. This change in Heather suggests that she has been better off because her parents have not been able to indulge her. She also begins to appreciate the way her parents earn their living.
