When I was in first grade I played Peter Pan with the
transformational imagination that the school pavement
between the building and the playground is the air in
the sky, and the Never-never-land was the playground.
I think Peter Pan personality (agelessness, never growing up)
is also called "Puer Aeternis" but that does not make it
irrelevant to autism in any way, I don't think.
I know someone like that... Randy .... Peter Pan,
forgot his last name... I think he has a website with music,
try google "Randy Peter Pan".
I'm not sure, but I can believe Michael Jackson may have
been this personality type also, unless they found serious
evidence that he was abusive. I really don't know.
