I just let our cleaning lady leave early because we're expecting a freak thunderstorm (this was after the forecast this morning said zero chance of showers for the rest of the week) and she left all the windows open in her house. She didn't have time to vacuum, and now I'm wishing it was pretty much any other chore she'd left undone because I hate vacuuming.
On the plus side, I had a clean bill of tooth health from the dentist and cleaned a full garbage bag of unused crap out of DS 1's room while he was still at school. My guess is that he's never going to miss any of it.
