Except Jane Austen didn’t write that line… and honestly, as romantic declarations go, it’s very, er, Edward Ferrarsish.
Also laughing at No. 10. “In vain I have struggled. It will not do. My feelings will not be repressed. You must allow me to tell you how ardently I admire and love you.”
Yes, Jane wrote that, but it’s not really that romantic. If it were, Mr. Darcy wouldn’t have had a struggle, or needed to repress his feelings. Just saying. (We much prefer “dearest, loveliest Elizabeth.”)
