Not really. I think "two rooms to go", not "x windows to go". There's no point in counting or adding, so I don't bother. Also, I only clean my windows once a year, if that. There's an hilarious story about a spider family having bred on the other side of a closed window I hadn't opened all year. That must have been at least 500 spiders. It was hard to even look through the window, so I eventually bothered to clean that one early. Maybe a mistake, seeing how half of those spiders than entered into my room, but, whatever. I don't mind spiders.
