Ever since my son started the 4th grade he has been lying a least every other day, it seems.
Last month when we were in wal-mart he told me he was tired and wanted to sit down. We found a nice bench in front of the store for him to sit on and I told him to sit there until I was done with my grocery list. I was away from him for about 15 minutes and when I returned to the bench he was gone. I ended up finding him in the electronic section of the store playing some video game which I had told him earlier that he could not play. I later found out that he was never tired and he went to play the video game as soon as I walked away from him. Since then I do not let him out of my sight when we go to wal-mart or any store.
Other times he will tell me little lies about things he has done or said. For example, I try to get him to drink more milk. So I tell him to drink milk at school. After school when I ask him if he drank milk with his lunch, he will lie and say yes when he hasn't. I know he is lying by the facial expression on his face, yet it takes forever for him to eventually tell me the truth.
My son never use to lie to me and now I am always doubting whether he is telling the truth. Is this normal for a child his age or is this some how related to his Aspergers?
