Posting about a teen relative. Things I have noticed are:
Very intelligent.
Excels at science.
Speaks with a very precise clipped accent that is not like his family at all.
Thinks nothing of asking an outrageous question in a social setting.
Says he sees colours when he hears music.
He's a lovely boy content being absorbed in his science. I cant help wondering that life might get more difficult for him as he grows older. Could he have Aspergers? His close family know he's not like other boys, but as far as I know not felt the need to investigate. I wouldn't want to interfere, though might offer my thoughts if it came up in conversation.
