The Teacher?

Last night after putting Kate and AJ in their separate rooms for bed, we hear over the monitor that someone is up and about. After about a minute of silence we hear talking, and since our monitor is not too clear, we can't tell who is talking, so Mike goes up to regulate. Before opening the door to Kate's room which had a light shining under the door, he hears AJ saying to Kate, "This is the letter C. What letter is this?" Mike didn't hear any response from Kate, so he opened the door. AJ is sitting on the edge of Kate's bed with an ABC book open reading to her. So sweet, and yet so funny, because she was sound asleep. We figure he went in there, turned on her bedside light, got the book and decided he didn't care if she was awake because he'd heard kids can still learn while they're sleeping.
