Suddenly, on the very dot of four, loud and anguished string music began, and a tiny twig of a girl dressed in an oversized corduroy space suit (below right) marched in. She was followed by a very similar girl in a ragged scrap of fleece blanket. Both wore expressions of grim misery. When the music dipped, I could hear waves of gentle shutter clicks from the camera pen, a sound like pixies clapping. I was quite shocked by how thin the models were. Their skinny ankles in their clumping shoes looked so pallid and fragile they made me want to weep. If that was Mr Anderson’s intention, I cannot applaud it. At the end he himself appeared, at a jog, also looking deeply unhappy. There was a smattering of clapping, but not much because most people were too busy Instagramming.
