You were not studying when she called.I was watching TV when she called.When the phone rang, she was writing a letter.While we were having the picnic, it started to rain.What were you doing when the earthquake started?I was listening to my iPod, so I didn't hear the fire alarm.You were not listening to me when I told you to turn the oven off.While John was sleeping last night, someone stole his car.Sammy was waiting for us when we got off the plane.While I was writing the email, the computer suddenly went off.
