Neil Gaiman, The Sandman
"Have you ever been in love? Horrible, isn't it? It makes you so vulnerable. It opens your chest and it opens up your heart and it means that someone can get inside you and mess you up. You build up all these defenses, you build up a whole suit of armor, so that nothing can hurt you, then one stupid person, no different from any other stupid person, wanders into your stupid life. . . . You give them a piece of you. They didn't ask for it. They did something dumb one day, like kiss you or smile at you, and then your life isn't your own anymore."
— Neil Gaiman, The Sandman, Vol. 9: The Kindly Ones
