While I generally do not cite the 1940 film for support for anything, I did like how Garson's Lizzy responds to Darcy's question -- Could you expect me to rejoice in the inferiority of your connexions? -- to congratulate myself on the hope of relations, whose condition in life is so decidedly beneath my own? She responds something to the effect "you could keep it to yourself." Disguise of every sort may be his abhorrence but sometimes you just keep your mouth closed. That would have been the mark of a true gentleman.
