You’re not friends. You’ll never be friends. You’ll be in love ‘til it kills you. You’ll fight, and you’ll shag, and you’ll hate each other ‘til it makes you quiver but you’ll never be friends.
Real love isn’t brains, children. It’s blood. It’s blood screaming inside you to work it’s will. I may be loves bitch, but at least I’m man enough to admit it.
