Examples of conformity in the novel Pride and Prejudice by Jane Austen?

Conformity in the form of marrying for convenience instead of love.

Eg 1: Mr Collins proposal to Elizabeth. Elizabeth is expected to accept Mr Collins' offer of marriage so she can save the rest of her sisters from destitution when their father dies. Elizabeth refuses to conform to the social norm of that era by rejecting Mr Collins' offer. Instead she decides to wait for true love (Mr Darcy).

Eg 2: Elizabeth's friend Charlotte Lucas accepts Mr Collins' offer of marriage as she is getting old and needs to find a husband because she has no money of her own. She conforms by marrying for convenience instead of love because she felt she had no choice.
