Some good friends of ours (to protect the guilty, we'll call them...“Steve” and “Julie“) were recently traveling with their 4 and 6 year olds by vehicle, and the kids were watching a DVD in the back seat.  When they got home (after dark), the kids ignored multiple parental requests to “shut it off”, “go inside”, etc., so our friends shut off the car and left the kids in it. 

“Steve” and “Julie” live in a pretty remote area, so when the lights are off...it's really dark.  Anyway, they shut lights off, went inside, and shut the garage door.  About 20 minutes later, the phone (in the house) rang.  When they answered, they found it was their six-year-old, calling from the cell phone...from the car in the driveway. 

He asked them to turn on the lights because it was too dark outside.
