Whenever we have had temps in the mid-thirties, I could not resist cracking open the east bathroom window for a bit during the midday. The winds have been horrific, but the fresh air was too good to leave totally outside. Today, as the tidy bowl lady made her weekly visit to smarten up the bathroom, I was taken aback as to how much dirt was on the shelf adjacent to the window that has brought in fresh air during this last week. I can only imagine from how far away these little grains of dirt came to land on my white shelf.
