Illumination

windows reflect
glowing in shadow
bright squares on grey

Sometime last year, I first noticed these strange orange-ish squares in the shadows of trees in the street in front of the library (enough prepositions for ya?). It took me a while, but I finally realized that the setting sun was reflecting off the windows of the library, and that light resulted in the bright spots within the shadows. Today, the first two lines came to me, and I liked the texture well enough to work on finding a third line to finish it.
