So if I asked you about art you could
           give me the skinny on every art book
           ever written...Michelangelo?
           You know a lot about him I bet. Life's
           work, criticisms, political aspirations.
           But you couldn't tell me what it smells
           like in the Sistine Chapel. You've
           never stood there and looked up at
           that beautiful ceiling. And if I asked
           you about women I'm sure you could
           give me a syllabus of your personal
           favorites, and maybe you've been laid
           a few times too. But you couldn't
           tell me how it feels to wake up next
           to a woman and be truly happy. If I
           asked you about war you could refer me
           to a bevy of fictional and non-fictional
           material, but you've never been in
           one. You've never held your best
           friend's head in your lap and watched
           him draw his last breath, looking to
           you for help. And if I asked you about
           love I'd get a sonnet, but you've never
           looked at a woman and been truly
           vulnerable. Known that someone could
           kill you with a look. That someone
           could rescue you from grief.
           That God had put an angel on Earth
           just for you. And you wouldn't know
           how it felt to be her angel. To have
           the love be there for her forever.
           Through anything, through cancer. You
           wouldn't know about sleeping sitting
           up in a hospital room for two months
           holding her hand and not leaving because
           the doctors could see in your eyes
           that the term "visiting hours" didn't
           apply to you. And you wouldn't know
           about real loss, because that only
           occurs when you lose something you
           love more than yourself, and you've
           never dared to love anything that much.
