Actually.

Karen: Tell me, if you were in my position, what would you do?
Harry: What position is that?
Karen: Imagine your husband bought a gold necklace, and come Christmas gave it to somebody else...
Harry: Oh, Karen...
Karen: Would you wait around to find out...
Parent: Good night!
Karen: Night, night. Happy Christmas!
[back to Harry]
Karen: Would you wait around to find out if it's just a necklace... or if it's sex and a necklace, or if... worst of all, it's a necklace and love? Would you stay? Knowing life would always be a little bit worse? Or would you cut and run?
Harry: Oh, God. I am so in the wrong. The classic fool...
Karen: [voice breaking] Yes, but you've also made a fool out of me, and you've made the life I lead foolish too.
