If Bob was the sort of person to tell people 'what they want to believe', I think he would have denied intending to include Fontelle in his estate to his daughters. (I like also how R tries to imply that there is a connection between their short second courtship/marriage and Bob's willingness to deceive, by using 'after all'.) I've often wondered how the topic came up. Did they ask Bob? Did he volunteer it? I do respect that he planned on including Fontelle and that he told them because it was the truth and right, but given his family, I do regret him having been honest. (I have no idea of whether he has any obligation to disclose his own will to his children, but I would guess not.)
I also think it's hard to imagine the daughters *not* going to AH's after the meeting with Bob. They surely wanted to vent, and could not do so in his front yard. Where else would they do so -- in a Perkins?
