The cool nights and warm days of the equinox mean we need neither heating nor air-conditioning, and the air flows freely in and out of the house. The windows are open (or as open as the stink bugs will allow) and what is inside the house is also outside.
I sit now beside an open window, listening to the acorns fall, thinking about the walls that separate us from the outdoors.
This is the time of year I turn my attention to neglected household chores. (If my family reads they will think, really? hmmm...) But even if I don't complete the task — even if the old curtains and the cluttered basement remain — that doesn't mean I'm not thinking about sweeping the house clean, freshening up the place, even painting.
At least the windows are open. If nothing else our house is being invisibly scoured by the low-humidity air of fall. It is a time of equilibrium; we are open to the air around us.
