Autism- Some children seek to please

My son always wants to please my husband and I. We never get mad with our son. We get upset with him at times like other good parents but we never get mad. When our son thinks we are mad at him he acts out. Fo instance. When we get up in the morning I ask him to open his curtains so the sun can shine through. His room is so dark.  One day I asked our son whom I will call "N". to open his curtains. Then I said in a slightly loud tone "Why do I have to tell you every morning to open your curtains?" I walked away thinking nothing else of it. N was upset, because he thought I was mad at him. He was jumping and humming in his angry hum. Then he asked, " Are you mad at me?" I had to spend 15 minutes reasurring him that I was not mad at him. He just kept humming, jumping, and asking was I mad at him. Finally I had to hold him, rock him, and talk to him in a softer tone to get him to calm down.
So, does your child seek to please you? Have you ever noticed what sets him or her off? What do you do to calm your child? Some Autistic children seek to please their parents. Need to feel perfect, and that they are always loved.
