my heart, your hands

i can feel the knife carving your love in my heart, you promised you wouldn't harm a hair on this fragile body, no that's not fair, but how can i trust you?, how can i trust you with my heart, in your hands closing your grip!, i'm so afraid that you'll leave me cold with my heart in your hands closing. try to sit here with closed eyes, it's not possible, cause how do i know that you'll be good doing the things that you know you should, yeah, how can i trust you?
