I have misgivings about a photograph I took of a window display. It was striking: a series of golden skulls with sport sunglasses, and below a copy of Dante, a crawling spider and a pair of reading glasses. Reflected in the window was a passing truck, a series of oak trees, and a cream and brick school building. I didn’t create the display and I wasn’t responsible for the view reflected in the window. What was I? I was the only thing you couldn’t see in the photograph.
