Jack: Maybe that's your purpose, too. Be a mother to those that ain't got one. A teacher to those who need lessons. We choose our purpose. Word you're lookin' for is destiny, and if you want to give God a good laugh, you tell him what you think your destiny is.
Elizabeth: And if I can't ever have children?
Jack: Then you can't have children.
Elizabeth: And you'll never be a father.
Jack: I guess it ain't my destiny. You're my destiny.
Elizabeth: You just said you can't choose destiny. You chose me.
Jack: One look at you, and I had no choice at all. Destiny. Look at all the things God had to give you to choose me. Poor judgment, bad vision, terrible taste in men. We take what life gives us. It's all we can do.
