All of that is classic Asperger's. Even if your mom has her own explanations, it sounds like her descriptions will support the diagnosis. Tony Attwood, probably the world's leading expert on Asperger's, proposed "the cure" for Asperger's children. He said simply take the child to his or her bedroom, and leave him or her alone. The child will probably have things in the room that he or she is interested in and will entertain himself or herself. During that time, while no demands are made on the child and the child is not expected to interact with others, all of the symptoms will disappear. Until, of course, the child needs to come out of the bedroom and/or face social situations and demands.

I did the same things too. I hated P.E. because I didn't know how to play the games, wasn't any good at it anyway, and watching the ants on the field was a lot more interesting than paying attention to the game. I could watch the ants all day. One of my teachers told my parents that if I wanted to have friends, I just needed to lower my standards. I have a son who says that he isn't interested in any other teenagers his age "because they all just want to do stupid things." He is planning to wait for them to all grow up so that they will be worth associating with. My brother taught himself to read at 4 years old and proclaimed himself a genius, then later refused to go to school because there was no point in it. All typical Asperger's characteristics.
