This post is for posterity's sake. Our thirteen year old son does know how to clean his room. He just needs the proper incentive. In this case, the incentive was the return of his current favorite Wii game that he has been grounded from for a month. He was due to get the game back on Saturday, but I guess every day counts. I only wish I had a before picture to show the drastic improvement! BTW, I did not check his closet, drawers, or under his bed; but don't tell him that!
