Nitpick: I think the intro example would be clearer if there were explicit numbers of grapes/oranges rather than “some”. Nothing is surprising about the original story if Beatriz got more oranges from Deion than she gave up to Callisto. (Or gave away fewer grapes to Deion than she received from Callisto.)
