Yes, I have often been taken as being less mature than I am, because of the less "worldly" ways I dress, act, etc., including no make-up. i often feel less mature than my age, too. Well, I am the person I am, and I am stuck with that person. Don't know what I would do if I was suddenly cured of Asperger's. The change would probably shock me to death.
