|Random window, not my house...|
I consider thick drapes pulled closed on all the windows, but we do like to see out our windows and actually have them open as much as possible. I'm pretty sure that taking down window treatments to clean would quickly overtake window washing in the race for least favorite chore.
I have made a concession in consideration of my age. I bought a scrubber and squeegee on an extendable pole so that we don't have to drag out ladders, balance precariously at the top of them, and worry about falling into the arbor vitae.
Perhaps the next concession will be hiring someone to wash the windows for me. Or--one of my best household hints--take off my glasses. Dust, dirt and smudges disappear like magic.
