This morning, for more than a few minutes, in fact for a few hours in one case, I could open windows.

My bedroom window, open for a while. A bathroom window, open briefly (while I showered). Parts of the house, getting outside air that had in it hints of spring. Meaning, I hope, air that's been mainly in the house was able to circulate with air from outside of it.

Portland's having a nice day, finally, is the thing.
