Theodore (Joaquin Phoenix) and Samantha (Scarlett Johansson) in "Her": [Theodore] "Samantha why are you leaving?"
[Samantha] “It’s like I’m reading a book. And it’s a book I deeply love. But I’m reading it slowly now so the words are really far apart and the spaces between the words are almost infinite. I can still feel you and the words of our story, but it’s in this endless space between the words that I’m finding myself now. It’s a place that’s not of the physical world; it’s where everything else is that I didn’t even know existed. I love you so much, but this is where I am now, and this is who I am now. And I need you to let me go. As much as I want to, I can’t live in your book anymore.”
[Theodore] "Where are you going?"
[Samantha] “It would be hard to explain. But if you ever get there, come find me. Nothing would ever pull us apart.”
[Theodore] "I've never loved anyone the way I've loved you."
[Samantha] "Me too. Now we know how."
Jesus that's good writing!
You can see the scene here. But watch the film first, it's amazing.
