DS10 has Asperger's too.
Yes, he can be very difficult in arguments, I normally have to ignore the argument, until he's ready to "talk" about it. I hate ignoring him, but hate arguing worse.
There are things that really bother him, mainly loud noises. We have a hard time at the local parades, fireworks shows, movies even. I had to buy him ear plugs, which helps somewhat. Even Disney, this past trip for the 1st time he wanted to meet characters, after 3 previous trips to the world before.
Also, he can not be given too many instructions at once. I have to break them down. I can't say go to the dryer, pull out the clothes, put them in a basket, bring to the living room and fold. I have to break it down to about 2 steps at a time for him, he also acts like I give him more to do with breaking it down. Where as I could give that same ENTIRE directions to someone else, he thinks they are getting less chores.
He's fairly social, but just acts out "oddly" sometimes, not bad behavior, just a bit over the top to most folks. But mainly at home and with family. He doesn't act out at school, except recess.
He excels in Math and Science (many Asperger kids do) and most go on to have highly successful careers. Mine struggled in reading for few years of school, but 3rd and 4th grade he has made a major comeback. Matter of fact, on his FCAT Writing test this year, he scored a 396 out of a possible 500, with the state average being 296.
Also, many become "obsessed" in one area. My DS does this, but does change the interest from time to time. When he was 2 to 3 years old it was letters. He didn't know the alphabet in order, but you could write any letter down and he knew it (and he didn't watch shows like Sesame Street nor did they work on this in his day care), he just knew them. Then it moved over to Pokemon, then Yu-gi-Oh, for about 2 years football (kid knew every stat, player, etc-he can even tell you a score from a game YEARS ago), then back to Pokemon, and now it's WWE wrestling.
They really like routine. Goodness, if we are running late in the mornings, he's gets bent out of shape, due to how things go & can get "changed".
