They dance now Wholly in air, it seems, Enhanced by atmospheres Of pure decorum. Rapt in the flow Of what they wear, we think Of light improbable rivers Moving through air. No strain escorts Their grace; they dance so well Their shadows stand and gape Along the walls, And we are pleased To feel our weight cascade Around our bones and down Into our chairs For we would never Spend our lives dancing, Dancing to an unmusical Mean end.
