I will be your wife mother cousin sister or whatever

You have this great idea. Why not let me be your everything? You will no longer be accountable or responsible For your actions, words or deeds. I will be your wife, mother, cousin, sister, whatever. You can point to me when things go wrong. I will be the scapegoat, the whipping boy. You can meander through the valley of life unscathed If you are sad, worried or depressed, it will be my fault I am queen of your world now, you are blameless and faultless If I am thrown into a dungeon, that is on me. A sinking log, because I allowed you to make me your everything.
