Here's the thing: Carlo Noppis, the son of a gentleman, insulted Petty, the son who sells charcoal, and said, "Your father is a beggar." Patty and her father told her husband that Carol had the courage to admit her mistake and sincerely repent, so they got back together.
I think Carlo's spirit of admitting mistakes is worth learning, but you can't bully the weak just because your father or mother is a gentleman. Carlo is not worth studying.
