The Good Wife2009

Eli Gold:
...Of course you're going to make your own decision; of course you're not going to do what Redmayne asks, but you don't tell him that. You don't tell him the truth.

[Alicia tries to speak]

Eli Gold:
No, shut up. Listen to me. You know the truth, here, in your heart. Good, be a Disney Princess, but don't tell money men like Redmayne anything but what they want to hear.

Alicia Florrick:
Even if it's a lie?

Eli Gold:
Yes, because it won't be a lie when you tell it. Absence of 'Yes' times 'Time' equals 'No.' That's the law. If you're in doubt you don't say no, you say "Thank you for your advice, all options are open to me, I plan to decide in the next 48 hours."

Alicia Florrick:
But what happens in 48 hours?

Eli Gold:
You do whatever you like, or you delay again. But you never, ever, say "no," because anything could happen.
