the missing piece
"The missing piece was alone again. For a long time it just sat there. Then... slowly... it lifted itself up on one end... and flopped over. And soon its edges began to wear off... liftpullflopliftpullflop... and its shape began to change... and then it was bumping instead of flopping... and then it was bouncing instead of bumping... and then it was rolling instead of bouncing.... And it didn't know where and it didn't care."
