As in not being as social & loud as the average person, having a different outlook on life, not liking or relating to typical teenagers, having different opinions, not caring about appearance/fashion, being more mature & mucking around less ect.
I wonder how it is possible for someone to be similar to me (a person with autism) but not have autism or for someone to be different (not really neurotypical) but not be autistic. If a person being different or not fitting in isn't because of autism, then doesn't it have to be something? I suspect that some quiet people are shy, many people with autism are shy & it could be more than shyness if they want to socialise but don't know what to say or don't relate to what people are talking about. Maybe there are so many more autistic people than is on the statistics.
I am not typical for a person with autism by the way.
