Martian Time-Slip

The way he sprinted about, on the tips of his toes, as if dancing to some unheard music, some tune from inside his own mind whose rhythms kept him enthralled. We are so pedestrian, compared to him, Steiner thought. Leaden. We creep along like snails, while he dances and leaps, as if gravity does not have the same influence on him as it does on us. Could he be made from some new and different kind of atom?
