Mrs. Antrobus :
Well, after living with you for 5000 years I guess I have a right to a word or two, don't i?
. . .
Calmly, almost dreamily.
I didn't marry you because you were perfect. I didn't even marry you because I loved you. I married you because you gave me a promise.
She takes off her ring and looks at it.
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."
