Oh, dear! Yes, certainly. I am sure Lizzy will be very happy – I am sure she can have no objection.
– Jane Austen
Pride and Prejudice, Chapter 18. Austen is famous for her devastating irony. Dramatic irony is used here when the stupid Mrs. Bennet, oblivious to Elizabeth’s feelings, gives Mr. Collins permission for a private audience with her daughter so that he can propose to her.
