Vee is my un-twin. She's green-eyed, milky blond, and a few pounds over curvy. I'm a smoky-eyed brunette with volumes of curly hair that holds its own against even the best flatiron. And I'm all legs, like a bar stool. But there is an invisible thread the ties us together; both of us swear that tie began long before birth. Both of us swear it will continue to hold for the rest of our lives.
