"Lydia will never be easy until she has exposed herself in some public place or other, and we can never expect her to do it with so little expense or inconvenience to her family as under the present circumstances."
"If you were aware," said Elizabeth, "of the very great disadvantage to us all which must arise from the public notice of Lydia’s unguarded and imprudent manner – nay, which has already arisen from it, I am sure you would judge differently in the affair."

– Jane Austen

Pride and Prejudice, Chapter 41. This is Mr. Bennet’s final word on Lydia’s wish to to go to Brighton, where the militia regiment is relocating. A believer in the passive parenting, Mr. Bennet doesn’t see any problem with Lydia’s trip. He thinks there will be little cost or inconvenience for the family if she goes. This is despite his eldest daughter Elizabeth’s warning that Lydia’s wild behavior will impact the family negatively. But Mr. Bennet turns out to be so wrong, and Elizabeth’s worst fears come to pass. This exchange is foreshadowing of the trouble that Lydia is about to bring down on the Bennets.
