I noticed that about my H, also. At the beginning he would only use the bathroom in the lower level, now he uses the one on the main level. When he was returning from a trip with a buddy, this was back in May, he even knocked on the door before he came into the house.
In the last couple of weeks he's been fixing things around the house, too. He put some stuff into the recycling bin last night, cut up all the boxes from the TV and stand.
