Remember back when your children were little and they wanted to help? What happened to dampen their enthusiasm. Both see the task in their own world view. Parents wanting to have the child do it right and not to create more of a mess. The child sees it as play or "helping" and may need guidance, acceptance, and encouragement. They may also needs to stop and start up again far more often. The child gets distracted easily and without a lot of encouragement and acceptance of effort they will gradually deminish in the interest in doing any task. Eventually jobs such as this are no longer fun or interesting.
Recently in my class a group of students were talking about things such as what direction the toilet paper should hang on the roll, can you squeeze toothpaste in the middle, and is there a right and wrong way to vacumn a floor. There were some in the group that looked like they could come to blows to defend their belief that their way was right and anything less than that was not only wrong, but it was not helpful as they would need to redo the job to make it "right." Then I brought up the loading of the dishwasher and washing clothes. Those are two that even more had views that there were rules about those areas that had to be followed or else the world as we know it might not go on. Who is the problem, the one who has a different way or the one that can't accept another person's helpfulness?
