This morning at the gym, a plasma screen television caught my eye. In general, I try to avoid looking at them – usually it is a stupid commercial and, besides, I should be looking where I’m walking – but the image was too alluring to pass up: a field of bright green grass dotted by miniature figures in red and yellow uniforms. The screen seized my attention, dazzling me for a spell. My eyes were pulled toward it like a nail toward a magnet. A soccer player had just scored a goal. He held an arm up victoriously and, drawing the muscles of his mouth and his neck into a sort of joyful scream, pierced the sky around his head jubilantly and repeatedly with a single pointing finger.
