She shook her head, and closed her eyes. I felt her weariness then, and with it, my own. I felt it dark and heavy upon me, darker and heavier than any drug they ever gave me - it seemed heavy as death. I looked at the bed. I have seemed to see our kisses there sometimes, I've seen them hanging in the curtains, like bats, ready to swoop. Now, I thought, I might jolt the post and they would only fall, and shatter, and turn to powder.
