What are some examples of hagars regrets of the things she used to do and realizes they were wrong?

As a consequence of her pride, Hagar has cut herself off from the natural flow of human sympathies. In her old age, trapped in her own negative perceptions and long habits of mind, she is unable to relate harmoniously with others. She is suspicious of people's motives and rejects their attempts to be pleasant. Sometimes she would like to be more reasonable, but a bitter or sarcastic remark will escape her mouth instead, in spite of herself.

Hagar's extreme alienation, the product of a closed heart, sometimes produces unexpected effects. Because she rejects others, she expects them in turn to reject her, so a simple act of kindness from someone else may produce a sudden burst of tears, as when a girl gives up her seat for Hagar on a bus.
