Stairway lines

I was wandering around school at the end of the day trying to find something to take a picture of. The kids have an early release at 1:30 on Fridays and teachers and staff stay until 3 and have meetings. Today my group had no meetings but I did a little straightening up in the behavior room and then went to look for a photo. I like the windows and the shadows in the stairway and there you have it.
Thank goodness it's Friday...
