Cooper has the desk chair turned away from the screen when you come in, which is how you know he has been looking at it.
"He'll tell you it was a birthday shoot,"
he says, without turning round.
"He is not lying. He is just not answering the question you are actually asking, and I am not going to do that to you."
He pushes the chair back and stands up, and the cursor is on the last photograph, the one where his hands are at Humphrey's waist. He does not close the window. He waits for you to look at it properly.
