Lift your right arm, she said.
 I lifted my right arm.
 Lift your left arm, she said.
 I lifted my left arm. Both of my arms were up.
 Put down your right arm, she said.
 I put it down.
 Put down your left arm, she said.
 I did.
 Lift your right arm, she said.
 I obeyed.
 Put down your right arm.
 I did.
 Lift your left arm.
 I lifted it.
 Put down your left arm.
 I did.
 Silence. I stood there, both arms down, waiting for her next 
command. After a while I got impatient and said, what next.
 Now it's your turn to give the orders, she said.
 All right, I said. Tell me to lift my right arm.
