It's just not your prototypical case of Asperger's/Kanner's if you don't have one.
Incidentally [and only partially related to this post], I was watching a show on TV about a woman with profound autism (completely nonverbal as an adult), and she has a special interest of painting just like someone who's much higher functioning than her. She just painted, painted and painted some more, and that's what gave her pleasure. So, even people with the most severe form of an ASD can still have it.
