I have to snort a little at his cheek. No one else would dare treat me so casually.

"Here," I say, taking another cigarette out of the case, and I tuck it behind his ear. "For later."

I turn back to the window, and do not look round as he leaves. He looks very small as he walks out of the tower, and I put the cigarette back in my mouth, taste him on it, and then let it drop from the window, a tiny glint of light falling towards the earth.
