Cleaning!
I have just discovered the power of the vacuum attachments. They are Wonderful. So far I've dusted all the trim along the wall, the window sills, the storage bins under my bed, my suitcases (they'd gotten quite dusty in storage), the keyboard, the printer, the piano keys, and my shoes. So much better than a damp rag. I think I'll keep going until the neighbors tell me to cease and desist.
