We sit behind the glass watching our hearts out on the smooth wooden floor moving in a choreographed blur. Holding our breaths with every feat, attempting to will perfection with our gaze, knowing we have no control over the lump-dove lump-dove of the shifting movements. We smile and nod through tight teeth at each missed beat, nearly the same way we smile and nod through tight eyes with every perfected measure. Soon the wooden floor is empty and there is a whirlwind of children all around us, everyone talking at once, getting their shoes and coats, and asking about dinner. Our instructor smiles and waves us on, until next week.
