I would love to gets some points for the question. How does Priestley present Sheila as a character who learns important lessons about herself and society? Inspector calls?

Priestly uses Sheila as a way of communicating that there is hope in the voices of the youth, and therefore, social change is on the horizon, when people like Sheila and Eric defy their parents. One example of Sheila’s perceptiveness is that she warns her mother not to “build a wall” between the inspector and themselves, as she understands the importance of responsibility - it would be foolish to hide from the inspector. Sheila insists on therefore, breaking down this wall. Perhaps this wall is a metaphor for the social partition between the upper class and the lower classes. Therefore this demonstrates that as the play has progressed, Sheila has adopted socialistic ideologies and her intelligence and morality is shown clearly. It is also worth noticing, that previously, she was shown in a more childish light, referring to her parents as “mummy and daddy,” she now becomes more assertive. She questions and even insults her parents, and with that, she is no longer her father’s easy way up the social hierarchy, but a voice for the oppressed in a capitalist society.
