Too late. I'm already nuts!

The thing that works for me is to sit down and have a talk with DS about how I know he is capable of reasoning out what I mean regarding ordinary requests (e.g. wash your hands, put your clothes away.) In the past, I have always meant "with soap, for long enough to be effective," and so on. I have always meant "folded and in the correct dresser drawer." I expect him to think about what makes sense because I don't want to give him a long list of instructions for every ordinary task. I ask him what it would be like for him if he were forced to communicate with me that way.

If he says he would be annoyed or frustrated, I say, "YES! That's how I feel."
