“To be sure you know no actual good of me, but nobody thinks of that when they fall in love.”

“You know, my Katie, if I could be someone who could take care of you, fall in love with you, make you fall in love with me, you know I’d do it. It would keep us together. I don’t want to lose you. But I can’t seem to fall in love with anyone who is good for me.”

“Nobody in my life has ever known me the way you do. Nobody in my life has ever made me feel as good as you do. You know me, you know everything about me, and when you leave me, you're going to be leaving the real me, the me nobody else has ever seen, that's who you're going to be rejecting.”

“I’ve never felt like this for anyone. And I’m not really sure what falling in love feels like, but I think—I know I have. With you.”

“You know, people can't fall in love with me just because I'm good at what I do.”

“The real purpose of the scientific method is to make sure nature hasn’t misled you into thinking you know something you actually don’t know.”
