I am just pointing out that whatever “superiority” she was referring to, she was wrong in doing so. There is no justifiable circumstance in which her attitude at that time would have been acceptable.
Yes, she pointed that out herself. People make mistakes. She corrected hers, with that man, then and there. That was the whole point of her story. She tied that in to several points about working together with the “other side of town,” getting an education, not expecting something for nothing, working hard etc.
