Very similar to high functioning autism. People with Asperger Syndrome(aspies) are interesting to talk to if you happen to have the same special interest as them. They're also very rigid. That means they'll get mad as hell if you sit in their special spot. They also have no creativity. They also think people with HFA are more "disabled". That is true once in a while, but not always.
Aspie: I have Asperger Syndrome.
Person with HFA: I have high functioning autism.
Aspie: I'm more high functioning than you!
Person with HFA: No one cares.
