"Happiness in marriage is entirely a matter of chance. If the dispositions of the parties are ever so well known to each other or ever so similar beforehand, it does not advance their felicity in the least. They always continue to grow sufficiently unlike afterwards to have their share of vexation; and it is better to know as little as possible of the defects of the person with whom you are to pass your life."
Jane Austen, Pride and Prejudice (Charlotte Lucas)
"Being now in her twenty-first year, Maria Bertram was beginning to think matrimony a duty; and as marriage with Mr. Rushworth would give her the enjoyment of a larger income than her father’s, as well as ensure her the house in town, which was now a prime object, it became, by the same rule of moral obligation, her evident duty to marry Mr. Rushworth if she could."
