One thing I love about this quote is that Darcy crashed and burned so badly that he remembers the month it happened. I bet he remembers it down to the second. “Dear diary, at exactly 12:03:26 on April 9th, 1813 Elizabeth Bennet obliterated my heart.”
If your feelings are still what they were last April, tell me so at once. My affections and wishes are unchanged; but one word from you will silence me on this subject for ever.
