I think a close friend of mine has this. Afterall it is "just" an autism diagnosis where everything doesn't line up neatly, why they call it atypical autism.

My friend knows lots about categories, especially birds, plants and cars. She is really good at that stuff. She is not much for routine, but neither am I. The thing that sets her apart the most from me is that she is totally autophobic, she wants to be in social situations all the time, around the clock. While I need a lot of own time. She doesn't seem to suffer any sensory overload despite being very sensitive to everything. Well, smell is her weakness and taste, she is sensitive to that. She is well liked because she is friendly and open. Very sociable. But she also misses tons of social cues that even I can see, and I know she is not very good at being social in the long run, she just needs to be with people.

She must be on some kind of spectrum because all my friends almost, have autism or ADD/ADHD.
