DS has aspergers. He's age 6
The most worrying thing about him is his lack of social skills
We were at a soft play centre yesterday and a little boy recognised him from school. The boy is is another class. The boy came over and said hi to DS in a friendly way. DS just scowled and looked away 
He didn't interact with the boy at all in the soft play centre - even though the boy seemed very friendly and was seeking DS out. Eventually the boy left DS alone.
DS does like some children in his class because he is familiar with them. Initially they were his enemies but he's got more familiar with them and thinks more positively of most of them now.
By acting so grumpy and negative he seems to attract the type of children who like to tease him a bit to get a rise out of him. I've noticed this a little bit when I've collected DS from his after school club.
So sometimes it's hard to know if he just thinks the other children are bullies or if they really are teasing him.
Do I just have to accept this is the way it is. Is there any hope if this improving? We've tried social skills classes but they don't seem to address DS's negative perception of other children .
