As we entered the locker room we saw a single bank of twenty-four lockers facing us. Two of the lockers in the upper row, in slots four and seven, withdrew back into the wall. It left the row looking like some gillette's broken grin for a moment or two, then new lockers slid into place. We both exchanged glances, then shrugged and located our appropriate lockers by the little laminated name plates slotted into them.
