Breaking Bad [Season 3, Episode 5]

When you have children, you always have family. They will always be your priority, your responsibility, and a man... a man provides. And he does it even when he's not appreciated or respected or even loved. He simply bears up, and he does it... because he's a man.

— Therefore, what conclusion am I left to draw? That you believe I have some proprietary kind of selfishness about my own formula. Some sort of overweening pride, I suppose, that you think simply overwhelms me, clouds my judgment.
— But it doesn't.
— Absolutely not. I simply respect the chemistry. The chemistry must be respected.
