An inspector calls quote "You don't seem to have learnt anything"

In context, Sheila is calling her father out on his lack of empathy and his failure to learn anything from the Inspector's visit. A young woman died, and each member of the household had a small part in her death. Mr. Birling continues to think selfishly of his Boown good.... the problem is swept under the rug. The Inspector's departure ended the ordeal. For Mr. Birling this means it's over. For Sheila, it means a new way of looking at life and the people around her.
