A Beautiful Mind

— Alicia, does our relationship warrant long-term commitment? Because I need some kind of proof, some kind of verifiable, empirical data.
— I'm sorry, just give me a moment... to redefine my girlish notions of romance. A proof? Verifiable data. Okay. Well, how big is the universe?
— Infinite.
— How do you know?
— Because all the data indicates it.
— But it hasn't been proven yet?
— No.
— You haven't seen it.
— No.
— How do you know for sure?
— I don't, I just believe it.
— It's the same with love, I guess.
