But there are still girls who make it bad for girls. Young girls are always showing me their diamond engagement rings. “Look, Fran!” It’s so old-fashioned.
Well, it's not clear that Fran knows that's what she did. Let's see: philosophical purity and solidarity with the Sisterhood, or the chance of a life of happiness?
It would be grotesque, but her utter contempt combined with her utter lack of self-awareness suggest that this is actually a brilliant piece of Dada-inspired Performance Art. You can almost picture her having to bite her cheeks to keep from laughing at the Bambi-eyed credulity of the interviewer - and the readers who will swallow this hook, line, and sinker.
Or she's just a clueless idiot.
