Sumer is icumen in.

I was gone for six days, and in that time summer arrived. Even in the dark of my late-night arrival on Friday, I could see how high the weeds and shrubs and grass had grown. And when I walked out on Saturday and found the peonies all over town, and the lilies starting to make their little buds, and the trees in somehow fuller leaf than when I'd left a week earlier, I knew it was here, really here.
