I give the chain attached to the radiator in her bedroom another tug. There’s enough slack for her to move about the room but not enough for her to get out. Her breath stinks like spoiled milk, so I inhale through my mouth. I try my best not to look directly at her face because if I do I won’t be able to go through with it. There are two thick layers of aluminum foil and garbage bags covering her bedroom windows. To secure the layers tight, I nail the quilt from off my bed to the wall. This has to work. Tomorrow I go back to school.
