lots of spectrum type traits in my family....my grandmother seems to have the trait of saying inappropriate things...and her eye contact seems almost, practiced??
lots and lots of great uncles on my mother's side who seem quite severly autistic, and have never really been able to look after themselves, of course, in those days they'd just be classed as "a little slow"
my great grandmother on my father's side was an eccentric piano player who loved sherry...so yeah, put that all up in a mixing pot and out pops me ^.^ x
