Harry's eyelids felt heavy, but he kept his eyes partly open, watching her. Before he was able to fall asleep properly, he'd have to take off his glasses, but then he wouldn't be able to see her expression as clearly. And he wanted to see it, because it warmed him, in a way that had nothing to do with physical exertion.
Her yawn was infectious, though, and he yawned too, closing his eyes. Drowsily he reached up to take off his glasses, and reached over to set them on the bedside table without opening his eyes. The laugh surprised him, though, and he did open them then, though his view of her was blurry now. "What's so funny?" he asked sleepily, wondering if his glasses had left an imprint on his nose from the way they'd been digging in there. He wouldn't be surprised.
