The airport scene from Casablanca

Rick and Ilsa  

ILSA
You’re saying this only to make me go.

RICK
I’m saying it because it’s true. Inside of us we both know you belong with Victor. You’re part of his work, the thing that keeps him going. If that plane leaves the ground and you’re not with him, you’ll regret it.

ILSA
No.

RICK
Maybe not today, maybe not tomorrow, but soon, and for the rest of your life.

ILSA
But what about us?

RICK
We’ll always have Paris. We didn’t have, we’d lost it, until you came to Casablanca. We got it back last night.

ILSA
And I said I would never leave you.

RICK
And you never will. But I’ve got a job to do, too. Where I’m going you can’t follow. What I’ve got to do you can’t be any part of. Ilsa, I’m no good at being noble, but it doesn’t take much to see that the problems of three little people don’t amount to a hill of beans in this crazy world. Someday you’ll understand that. Now, now…

Ilsa’s eyes well up with tears. Rick puts his hand to her chin and raises her face to meet his own.

RICK
Here’s looking at you, kid.
