What is the conflict in "Revelation" by Flannery O'Connor?

Revelation by Flannery O'Connor features both a major and a minor social conflict.

The minor social conflict concerns the main character, Mrs. Turpin, and the "white trash woman" over whom she passes judgement. Mrs. Turpin considers herself of a higher social ranking than the uneducated white-trash woman, and when the latter dares to interject and interrupt a conversation Mrs. Turpin is having with a third party, Mrs. Turpin views it as a gross social violation.

The major conflict of the story is again between Mrs. Turpin and a young woman in the waiting room. The conflict is largely developed by a series of facial expression between the two, including a look the girl gives her which she describes as the "ugliest face she has ever seen anyone make." The conflict between the two characters is ultimately realized as a physical confrontation, with the young woman striking her with a book. Mrs. Turpin, who believes herself to be a good and moral person of high standing, cannot understand why she should be the victim of this attack, and the conflict is then internalized as she becomes unable to reconcile her self-perception with the actions of others towards her.
