"Oh! you are a great deal too apt, you know, to like people in general. You never see a fault in anybody. All the world are good and agreeable in your eyes. I never heard you speak ill of a human being in your life."
"I would not wish to be hasty in censuring anyone; but I always speak what I think."
"I know you do; and it is that which makes the wonder. With your good sense, to be so honestly blind to the follies and nonsense of others! Affectation of candour is common enough – one meets with it everywhere. But to be candid without ostentation or design – to take the good of everybody’s character and make it still better, and say nothing of the bad – belongs to you alone. And so you like this man’s sisters, too, do you? Their manners are not equal to his."

– Jane Austen

Pride and Prejudice, Chapter 4. After the ball in Meryton Elizabeth and Jane hold a post mortem, during which they discuss Charles Bingley’s interest in Jane and also what Elizabeth says is the bad behavior of Bingley’s sisters. Elizabeth accuses Jane of being too quick to see the good in everybody and being blind to people’s faults. But Jane is reluctant to criticize the Bingley sisters and tells Elizabeth that she is too quick to judge others harshly. Elizabeth’s suggestion that her sister’s judgment of people is flawed turns out to be ironic, since Elizabeth turns out to be a poor judge of Mr. Darcy’s and Mr. Wickham’s characters, which almost costs her her happiness. This exchange is also foreshadowing of how Jane will put her own happiness at risk by failing to see the bad intentions of her manipulative false friend Caroline Bingley.
