"Mr. Collins appears to be very fortunate in his choice of a wife."
"Yes, indeed, his friends may well rejoice in his having met with one of the very few sensible women who would have accepted him, or have made him happy if they had. My friend has an excellent understanding – though I am not certain that I consider her marrying Mr. Collins as the wisest thing she ever did. She seems perfectly happy, however, and in a prudential light it is certainly a very good match for her."
– Jane Austen
Pride and Prejudice, Chapter 31. Mr. Darcy believes that Mr. Collins is very lucky in his choice of a wife in Charlotte. However, Elizabeth is not so sure that her friend got the better end of the bargain. Charlotte is one of the few sensible women that would have married Mr. Collins, Elizabeth says. But she concedes that Charlotte appears happy and from the practical point of view it is a good match for her. Elizabeth is also being contradictory, describing Charlotte as sensible, but saying that her choosing Mr. Collins is not the wisest thing she ever did.
