In Southern society, widows are supposed to act like they are buried with their dead husbands. Scarlett finds this horribly oppressive; she is still young, and she barely knew Charles, so she’s not actually sad he’s gone. However, she is particularly unchanged by marriage, motherhood, and bereavement.

Her lack of interest in the monumental things that have happened to her shows that she’s still young and selfish.
