I’m drawing a cityscape in pastels, a new medium for me, and not really knowing what I was doing, I sketched the outline in black and then filled in the buildings as blocks of color. It looked pretty cartoonish. My teacher came and looked at it and said, “Now put the shadows in,” and once the buildings had shadows, pop! They suddenly looked real. I think a lot of things work that way.

My daughter loves her shadow. Like Robert Louis Stevenson, she thinks of it as a friend. I hope that’s always true.
