“think I am beginning to understand why grief feels like suspense,” C. S. Lewis wrote after the death of his wife. “It comes from the frustration of so many impulses that had become habitual. Thought after thought, feeling after feeling, action after action, had H. for their object. Now their target is gone. I keep on through habit fitting an arrow to the string, then I remember and have to lay the bow down. So many roads lead thought to H. I set out on one of them. But now there’s an impassable fron-tierpost across it. So many roads once; now so many cul de sacs.”
