Your description of your son, with the overly goofy and physically annoying....that sounds like my son. My son is diagnosed Aspeger's, but he has very mild visible signs of it. One thing he does have is a very poor sense of other people's personal space and what is uncomfortable for them. I am not saying he does have it, but that is usually an indication to look further.
There is a lot of social training and therapy that can help a child learn and work around some of the issues that Aspeger's children have relating to others.
