My focus this GR is on deception. I'm going to expand that a bit to include exaggeration and blindness. There will probably be some crossover with Line's focus on gossip.
The first deception I noticed was Mr. Bennet in Ch. 1, pretending he was not going to visit Mr. Bingley, then surprising his family with a fait accompli. What is his motive? Is it his "reserve" (end of Ch. 1), causing him to conceal some of his actions from his annoying wife? Or his "caprice," changing his mind and going in secret after deciding, due to the tiresome converation with Mrs. B., that he would not visit Mr. Bingley?
It's been more than three-and-twenty years since I first read this, and I still do not fully understand his character!
