how do we tell DB at 33?! He will be so pissed off now we didnt tell him as a child. They live in fear of him requesting his medical records from GP for a job or something!
That's beyond appalling. They really need to sort this out and soon. They have treated his medical dx as something to be ashamed of, something to be hidden away. Did they think if he didn't know then he's somehow grow up NT? Poor, poor man.
Here are some rhetorical questions for you to reflect on.
How is he coping in the NT world workwise, working relationships wise and 1to1 relationship wise?
If he has the stereotypical male presentation and works for a tech firm or in academia or other career where it's almost more geared-up for autistics, he may be having a great life and not need any interventions because he's chosen a path that is very accepting of autistic people.
Similarly, if he's in a long term relationship with someone who understands him and caters for his differences, again it won't be impacting his life adversely, so he could be oblivious but happy.
However, if he's constantly feeling anxious (like an alien has been a common analogy) and is now resigned or depressed because no matter what he does either workwise or careerwise, he feels as though he's from another planet. Everyone else knows how to notice and interpret a shrug or sarcastic voice or a complement that's really an insult but he doesn't, he takes everything at face value and often finds himself a target for ridicule and being ripped off. No-one else will need to decompress after a minor social event, no-one else will be so irritated by something that they could literally scream or run away, but he might.
He'll never know WHY people treat him badly until he's told it's because of his neurodiversity. Until it's explained to him that NT people use a completely different way of communicating and how they do that, so he can understand, or ask for things to be presented in a way he does understand.
Does he have children? If he does, there's a possibility one or more could be autistic and he could discover his own autism if they were diagnosed. Many parents of children being diagnosed at the moment have thought 'wait a minute, that's me they are describing' when answering questionnaires at assessment interviews. Many parents don't recognise autism in their own children because it's the parent's 'ordinary' to behave in the same way their child does.
OR, it's always possible he's realised he's a different thinker and he's looked up the way he sees the world online and found the AQ test and thought, oh yes, that's me, no point in pursuing a diagnosis because all is fine.
OR, he'll have tactless colleagues who will outright ask him if he's autistic there and then when he's done something they think could suggest that. Do they have a nickname for him like 'wiki' or 'Robot' or 'Mr Spock'(Star Trek) or 'Sheldon'(Cooper).
