Breakfast at Tiffany's (1961)
Paul Varjak: Holly, I'm in love with you.
Holly Golightly: So what.
Paul Varjak: So what? So plenty! I love you, you belong to me!
Holly Golightly: No. People don't belong to people.
Paul Varjak: Of course they do!
Holly Golightly: I'll never let ANYBODY put me in a cage.
Paul Varjak: I don't want to put you in a cage, I want to love you!
Holly Golightly: It's the same thing.
Paul Varjak: No it's not. Holly...
Holly Golightly: I'm not Holly. I'm not Lula Mae, either. I don't know who I am! I'm like cat here, a couple of no-name slobs. We belong to nobody and nobody belongs to us. We don't even belong to each other.
Paul Varjak: You know what's wrong with you, Miss Whoever-you-are? You're chicken, you've got no guts. You're afraid to stick out your chin and say, "Okay, life's a fact, people do fall in love, people do belong to each other, because that's the only chance anybody's got for real happiness." You call yourself a free spirit, a "wild thing," and you're terrified somebody's gonna stick you in a cage. Well baby, you're already in that cage. You built it yourself. And it's not bounded in the west by Tulip, Texas, or in the east by Somali-land. It's wherever you go. Because no matter where you run, you just end up running into yourself.
