Sitting cross-legged on her bed, I watch her take out her gear. She’s been smoking so much the room stinks of it. Over the last few weeks, I’ve seen her do it so often I’ve resisted the urge. It’s surreal, like I’m watching me from outside my body. My willpower is fragile at the best of times, but my resolve is always weaker in the evening. I feel a dread and a revulsion for what I’m about to do, but there’s a stronger feeling, an unutterable longing. I crack. ‘Give us a line,’ I say.
