And then suddenly I hear his footsteps approaching. He's behind me, thirty feet away, at a guess. No wonder I couldn't see him. I should turn. Right now I should turn. This is the moment that it would be natural to swivel round and greet him. Call out a hello; wave my phone in the air. But my feet are rooted to the spot. I can't bring myself to move. Because as soon as I do, it will be time to be polite and matter-of-fact and back to normal. And I can't bear that. I want to stay here. In the place where we can say anything to each other. In the magic spell. Sam pauses, right behind me. There's an unbearable fragile beat as I wait for him to shatter the quiet. But it's as though he feels the same way. He says nothing. All I can hear is the gentle sound of his breathing. Slowly, his arms wrap round me from behind. I close my eyes and lean back against his chest, feeling unreal.
