Someone in my life was recently talking about masked autism in adults:

The naive clinician or therapist asks, "do you have difficulty with socks?" and the autistic adult says no and concludes they don't have autism

The really knowledgeable one asks, "so tell me about socks," and receives a massive infodump about the very specific choices they made about socks and comfort

@recursive I was just discussing this with my ex, about her sister.

We just went through an ADHD (with ASD trait) diagnosis with our son, and she's starting to realise she has ADHD, and that her sister has massive ASD traits that she's spent years masking.

To the point that her ex husband and her ran a successful cafe in a trendy Sydney suburb, and she was running front-of-house.

Masking is easy for some, and it's how we all learned to survive before there were diagnoses
