Instinctively, and against my better judgement, I pull her closer to me. She rests her head on my shoulder as if it is the most natural thing in all the worlds to do.But it's a mistake. I become aware of her heart beating, her lungs expanding with every breath, her skin beneath my touch.She moves, and her head slides to my chest. Shifting into sleep, she wraps her arm around my waist. Now I'm aware of my heart beating too, slowly, in sync with hers. I know I should push her away. But if my life depended on it, right now, that would be impossible.
