It is true; he told her early on never to touch anything on his desk, and she...well, she wasn't sure if he had wards on the drawers so she hasn't done anything more than skim through what he leaves lying out on top of the polished wood surface, which wasn't anything interesting. She clasps her hands together, and her eyes meet his for a long moment, and she feels a spark of silly success when he is the one who looks away first.
