Don't be superior. Everyone drinks blood. Blood is a word that means alive. You can do without almost anything: arms, legs, teeth, hope. But you can't do without blood. Lose even a little and you grow slow and stupid and not yourself at all. We are all of us beautiful and complicated vessels for carrying blood the way a bottle carries wine. I suppose you think there's no blood in your roast beef? Life eats life. Blood makes you move, makes you blush, makes the pulse pound in your brow when you see your love walking across a street toward you, makes your very thoughts fly through your brain. Blood is everything and everything is blood.
