The Godfather1972

Michael Corleone:
I'm working for my father now. He's been sick, very sick.

Kay Adams:
But you're not like him, Michael. I thought you weren't going to become a man like your father. That's what you told me.

Michael:
My father's no different than any other powerful man – any man who's responsible for other people, like a senator or a president.

Kay:
[laughs] You know how naïve you sound?

Michael:
Why?

Kay:
Senators and presidents don't have men killed.

Michael:
Oh, who's being naïve, Kay? Kay, my father's way of doing things is over, it's finished. Even he knows that. I mean, in five years, the Corleone family is going to be completely legitimate. Trust me. That's all I can tell you about my business.
