Robert is such an arrogant know-it-all. He knows exactly how everything should be done, from toothpick cases to educating a young man, to cottage designs, to the proper way to set up a ball in one!
He's a name-dropper, too. This reminds me of Tom Bertram, who's always saying 'my friend so-and-so' but in Tom's case, I think the people really are his friends. I wonder if Robert Ferrars is really 'friends' with the Lords and Ladies he talks about.
