"Poor soul!" cried Mrs. Jennings, as soon as she was gone, "how it grieves me to see her! And I declare if she is not gone away without finishing her wine! And the dried cherries too! Lord! nothing seems to do her any good. I am sure if I knew anything she would like, I would send all over the town for it. Well, it is the oddest thing to me, that a man should use such a pretty girl so ill! But when there is plenty of money on one side, and next to none on the other, Lord bless you! they care no more about such things! -- "
"The lady then -- Miss Grey I think you called her -- is very rich?"
"Fifty thousand pounds, my dear. Did you ever see her? a smart, stylish girl they say, but not handsome. I remember her aunt very well, Biddy Henshawe; she married a very wealthy man. But the family are all rich together. Fifty thousand pounds! and by all accounts it won't come before it's wanted; for they say he is all to pieces. No wonder! dashing about with his curricle and hunters! Well, it don't signify talking, but when a young man, be he who he will, comes and makes love to a pretty girl, and promises marriage, he has no business to fly off from his word only because he grows poor, and a richer girl is ready to have him. Why don't he, in such a case, sell his horses, let his house, turn off his servants, and make a thorough reform at once? I warrant you, Miss Marianne would have been ready to wait till matters came round. But that won't do, now-a-days; nothing in the way of pleasure can ever be given up by the young men of this age." (30.7)
Money, then, is what drove Willoughby to throw over Marianne – and we, like Mrs. Jennings, can understand it, but still feel unsympathetic. It seems like a pretty lame excuse to us.
