Too Smart for His Own Good?

A couple of weeks ago, I had D babysit Kaeden. Apparently he got into trouble, and she gave him his very first time out. She told him he had to stay in one spot and not move until she said okay. He tried to run away, and she stayed there with him, explaining again. Then his little lips started quivering and he apparently cried for about a minute. But then, he stayed there until she told him he could go play again! He's pretty quick to catch on, eh?!
