marry you because I loved you. I married you because you
gave me a promise. That promise made up for your faults.
And the promise I gave you made up for mine. Two imperfect
people got married and it was the promise that made the marriage.
And when our children were growing up, it wasn't a house that
protected them; and it wasn't our love that protected them -
it was that promise.
Thornton Wilder, The Skin of Our Teeth
