Julia Quinn said this quote

She’d ceased spying upon him, that was true, but the damage was done. Every time he sat at his desk, he could feel her eyes upon him, even though he knew very well she’d shut her curtains tight. But clearly, reality had very little to do with the matter, because all he had to do, it seemed, was glance at her window, and he lost an entire hour’s work.It happened thus: He looked at the window, because it was there, and he couldn’t very well never happen to glance upon it unless he also shut his curtains tight, which he was not willing to do, given the amount of time he spent in his office. So he saw the window, and he thought of her, because, really, what else would he think of upon seeing her bedroom window? At that point, annoyance set in, because A) she wasn’t worth the energy, B) she wasn’t even there, and C) he wasn’t getting any work done because of her.C always led into a bout of even deeper irritation, this time directed at himself, because D) he really ought to have better powers of concentration, E) it was just a stupid window, and F) if he was going to get agitated about a female, it ought to be one he at least liked.F was where he generally let out a loud growl and forced himself to get back to his translation. It usually worked for a minute or two, and then he’d look back up, and happen to see the window, and the whole bloody nonsense cycled back to the beginning.
