My family just watched the three best versions of P&P -- BBC 1980ish, Jennifer Ehle and Colin Firth, and Keira Knightley and Matthew Mcfaddyn. I haven't read the book in probably 10 years, maybe when I'm recovering from upcoming surgery. I try to read that along with Persuasion, S&S, and Northanger Abbey every five years or so, the meatier ones less often.
Oh, I think Lizzie said this when her aunt and uncle were taking taking her to the Lake District, not too long after an encounter with the "last man she'd ever marry."
