At a ball, Lizzy Bennet is insulted by Mr.Darcy, when he refuses Mr.Bingely's offer of an introduction to her. But Lizzy reports this slight to her friends in jest. Her playful and easy going nature are revealed by this incident. When Lizzy and Jane are discussing Mr.Bingely's sisters, Lizzy shows herself to be very observant. Also according to the author, her judgment is not troubled by any self absorption and her temper is also not as pliant as her sister's.
Lizzy's physical appearance is described as being light and pleasing by Mr.Darcy. Though he initially remarks that there is not one pleasing feature in her face, he admits that the intelligence in her dark eyes have a charm all their own which renders her face intelligent. Her manners are also said to be playful if not exactly fashionable.
After his initial dislike, Mr.Darcy reverses his opinion and tries to get to know her better. But Lizzy sticks to her initial opinion of him and refuses to give him a chance. She is sarcastic in conversation with him and assumes that he is continuing to judge her poorly, not being aware of the reversal in his opinion.
Sometime later an invitation arrives, asking Miss Jane to come to tea at Netherfield, the residence of Mr.Bingely. Due to a mishap she falls ill and is forced to stay the night.
