Diane: How long were your aunt and Uncle Nathan married?
Sam: How long? Uh, why- I don't- Uh, 50... 40, 50 years. I don't know.
Diane: My, my, my. It must be very hard on her.
Sam: Oh, yeah. Oh, just imagine. OK. I'm off now.
Diane: Sam, do you know what the secret of a long-lasting relationship is?
Sam: No, I don't, Diane, but I will think about it as I drive along, okay?
Diane: It's honesty, Sam. Once honesty leaves a relationship, the relationship is over. Finished. Empty. For example, if one of us were to lie to the other now, it would be a crime of the soul. A death of a spirit. Our lives would be diminished beyond redemption.
Sam: Diane, this is not one of the world's great goodbyes here.
Diane: [laughs] Of course. You'd better go. Be careful. There'll be a lot of skiers on the road and you know how insensitive people on their way to a ski weekend can be.
Sam: Okay, okay. [exits]
