Boy of three or four walking slowly along the #1 downtown subway platform at 86th Street. Blue and white sneakers. Jeans. His father three steps ahead.
The downtown express—always the loudest by far of the four trains coming through—thunders through the middle of the tunnel. Next stop 72nd Street, if it remembers to.
Father plugs his ears with his forefingers.
Boy makes an arch, a bridge, with his arms—his fingers intertwined a foot above his head, his shoulders pulled up vertically to cover his ears.
He continues to walk like this until the train passes.
