Imagine a world without love and romance. No love poems or love letters. No Romeo and Juliet. No Sir Lancelot and Guinevere. No Clark and Lois. No Mikey and Minnie. No heart-shaped boxes of chocolates or long-stemmed roses that say "I'll love you forever." No heights of passion or depths of despair. In love, we are at our best and our silliest. In love, we are the only two people on the planet, certain that no others have felt the same way we do.
