This is another quote I had seen I think on a journal at the Jane Austen Centre in Bath, but I couldn’t place it. It’s actually Darcy, talking to Miss Bingley. He tells her he’s been thinking of Elizabeth’s fine eyes, and she asks, “When am I to wish you joy?” To which he replies:
“A lady’s imagination is very rapid; it jumps from admiration to love, from love to matrimony in a moment. I knew you would be wishing me joy.”
Pride & Prejudice, volume 1, chapter 6
I’m afraid he is right!
