You have chosen your fault well. I really cannot laugh at it. You are safe from me.

– Jane Austen

Pride and Prejudice, Chapter 11. When Mr. Darcy says that his faults lie not in his understanding but in his temper, Elizabeth is at her merciless best with her ironic response. She concludes that his faults are not to be laughed at. But she is laughing at and ridiculing him in what she says.
