Darcy's pride towards Elizabeth is expressed at his first introduction in the novel at the ball he attends with Bingley. He famously refuses to dance with Elizabeth, in words that show him to be a very haughty individual:
She is tolerable; but not handsome enough to tempt me; and I am in no humour at present to give consequence to young ladies who are slighted by other men.
Of course, the fact that these remarks are overheard by Elizabeth herself does nothing to lessen their impact. She leaves that ball thinking Mr. Darcy to be one of the proudest individuals she has never met, and this causes her to vow never to dance with him again. He does little better when he first proposes to her, as he manages to do so in such a way as to insult Elizabeth and her family whilst also clearly highlighting the difference in their social position.
