first you build up a whole suit of armor,so that nothing can hurt you.then one stupid person no diffrent from any other stupid person,wanders into your stupid life and you give them a piece of you. next day your life isn't your own anymore. that stupid person just open up your heart and it means that someone can get inside you and mess it up,then the soul-hurt is here,a real gets-inside-you-and-rips-you-apart pain.
