My family is not NT at all! DH, DD1, DD2, and DGD are all ND, as is another relative, all descended from MIL, who we suspect had ASD! They have between them any combination of ASD, ADHD, developmental language disorder, dyslexia, dyspraxia, sensory processing disorder, anxiety, social anxiety and OCD! They are all very different!
DH can be the life and soul of the party - very funny and quick witted, due to his mind going off at tangents in an instant. DD1 was the same, whereas DD2 has social anxiety. DD1 is very organised, but DD2 is totally disorganised. DD1 struggles to decode, but can comprehend the story; DH and DD2 can decode brilliantly, but don’t understand what they read! DH and DD1 can talk for England, DD2 only believes in functional communication, and doesn’t understand the point of small talk at all. DH has always been able to use hyperfocus at work, which made him very successful, DD2 needed methylphenidate to work.
Nobody can assume we live a NT life - actually life with someone, who is hyperactive is exhausting!
