How does the Ginnie Sue Pastor story make Jeannette question her original opinions of other people?

Jeannette had always been curious about the whores at the green lantern, and when she went to Ginnie Sue's, she expected to learn what whoring was really like. When she met Ginnie Sue, however, she came to see that Ginnie was just a mom.... just a woman like any other. The only difference being that she took to whoring to keep her children fed. Thus, Jeannette learning that preconceived notions were not always accurate.

While I was sitting there talking to Ginnie Sue, I'd even forgotten she was a whore. One thing about whoring: It put a chicken on the table.
