Scene: Getting into the car to take Ben to a friends for a sleepover that he has been waiting for all afternoon. "Is it time to go yet?" "Mom, can we leave yet?" "Is it 6:15 yet?" "Why can't we leave now?"
Anyway... to the car.

Ben: "How do the lights go on when you open the door?"
Me: "I don't know Ben"
Ben: "Do you push a button?"
Me: "No Ben"
Ben: "It's cool"
Me: "I know Ben"
Ben: "Mom"
Me: "What Ben"
Ben: "How do the lights go off?"
Me: "We're here... see you tomorrow Ben"
