We do not suffer by accident. It does not often happen that the interference of friends will persuade a young man of independent fortune to think no more of a girl whom he was violently in love with only a few days before.
– Jane Austen
Pride and Prejudice, Chapter 25. Elizabeth says this to Mrs. Gardiner about the break-up between Jane and Mr. Bingley. The "interference" she refers to is by Mr. Darcy, whom she blames for persuading his friend Bingley to pull away from Jane despite being "violently in love" with her.
