It opens your chest and it opens your heart and it means someone can get inside you and mess you up. You build up all these defenses. You give them a piece of you. They don't ask for it. They do something dumb one day like kiss you, or smile at you, and then your life isn't your own anymore.
Love takes hostages.
It gets inside you. Not just in the imagination. Not just in the mind. I hate love. Gaiman Sometimes being a friend means mastering the art of timing.
