IF YOU DRINK THE JUICE OF A FRUIT, AND A VAMPIRE DRINKS THE BLOOD OF A HUMAN, THAT MEANS THAT THE JUICE FROM THE FRUIT WAS IT'S BLOOD, AND THE BLOOD FROM US WAS OUR JUICE. WHICH MEANS HUMANS ARE VAMPIRES TO FRUIT, AND VAMPIRES ARE ACTUALLY DRINKING HUMAN JUICE. SO, IF HUMANS ARE VAMPIRES, AND VAMPIRES DRINK HUMAN JUICE, THAT CAN ONLY MEAN THAT HUMANS ARE ACTUALLY CANNIBALS. Philosoraptor.
