One of my closest friends has a son (I will call him Paul) with Aspergers. In fact I met her at an early intervention program that her and my son were attending (my son has cerebral palsy).
I knew Paul from when he was three years old until he went to live with his father on the Mainland when he was 14. It was sometimes difficult to determine what of Paul's behaviour was a result of the Asperger's and what was a result of poor discipline. My friend would let him get away with bad behaviour stating it was a result of his condition.
For example, if adults were talking and not paying him the attention he wanted he would grab the adult by the chin and twist their head around to face him. I hated him doing it and I told him he shouldn't touch people without their permission. His mother insisted he did it because of the Aspergers. I said to her "I am not going to let him do it to me" and I told him if he wanted my attention he should say "Excuse me, may I interupt?" and I would answer him, adding that if he touched me again without my permission I would slap him. He never did it to me again though he continued to do it to others.
He also used to look it handbags without permission. I caught him with my handbag one day and pulled it of him telling him that I wouldn't have him invading my privacy., once again threatening him with a slap if he did it again. He stopped looking in my handbag.
He used to compulsory touch objects. I didn't totally stop him from doing it but I did teach him there were certain items in my home that he had to leave alone.
He used to fret about time. If his mother and I took him shopping he would want to know which bus we would catch home. We would say the 2.15 and if, it looked like we wouldn't make that bus in time he would start to panic and no matter how much we explained that we would catch the next bus he would get more and more worked up about missing the bus. Not only this, but he also memorised the bus-times and would get upset if the bus was late, or if it didn't reach his street by the time is said in the bus timetable (which were only appoximate times). One day we got on the bus in the city, travelled over the bridge and stopped at a shopping centre where there was a large crowd of people waiting to catch the bus. Paul got really upset because he said the people were too slow getting on and the bus wouldn't reach his bus-stop by 2.35 (the time given on the bus timetable). He shouted at the bus driver, saying he should leave the people behind so that the bus could stick to the timetable.
He also memorised the entire Guinness Book of Records and would always be quoting it.
