Love actually - Karen and Harry scene

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 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.
