That his two sisters and Mr. Darcy, however, should have such an opportunity of ridiculing her relations, was bad enough, and she could not determine whether the silent contempt of the gentleman, or the insolent smiles of the ladies, were more intolerable.

– Jane Austen

Pride and Prejudice, Chapter 18. Elizabeth is embarrassed by the behavior of her family at the Netherfield ball. She is even more mortified that it has given Mr. Darcy and the Bingley sisters Caroline and Louisa so much ammunition to ridicule her family.
