John Winchester: Sammy. I don't think I ever told you this... but the day you were born, you know what I did? I put a hundred bucks into a savings account for you. I did the same thing for your brother. It was a college fund. And every month, I'd put in another $100 until.... Anyway, my point is, Sam... that this was never the life that I wanted for you.

It never occurred to me what you wanted. I just couldn't accept the fact that you and me, we're just different.
