Shiela and Eric have definitely changed - and Sheila even more so than her brother. At the beginning of the play, both Sheila and Eric are infantilised by their parents (which means they are treated like small children.) Both Eric and Sheila live up to this by bickering over the dinner table. During the Inspector's visit, however, we can see Sheila growing up. She refuses to leave the room when asked, she stands up to her parents, and, at one point, reminds them that "
I'm not a child, don't forget." And after the inspector leaves she remains determined and resolute in her desire to stand up to her parents: "
The point is, you don't seem to have learnt anything." Eric is similar, in that he also stands up to his parents, but often is best summarised by the line: "
Sheila is right." In this play, the younger generation change, and Sheila is at their head.
