"Hermione, please," Harry scoffed, though he was grinning. She had responded just as he had come to expect, and it was terribly satisfying, not to mention comforting. He bent his leg and straightened it several times, rocking the chair back and forth, just to annoy her. "I am an Auror, as you say. I survived a war. I think I can handle myself in a chair."
He paused again. His grin faded into his coffee cup as he thought about how to answer her.
"I... well, no. See. Lately my eyes have been bugging me a little. Like sometimes my eyes are blurrier with my glasses on, and then when I take my glasses off I can see all right." He pressed his lips together. He wouldn't mention the growing taller bit. Not yet. He'd see how she reacted to this, first.
