Socially, in my immediate environment, I don't see the big picture. Mum does and she's NT. She's amazing, it's like still having a grown up around for the way that she manages people's needs. Eg my stepdad will need to use the computer. I will need to not have an Apple computer on because of the light. She figures both our needs out and tells my stepdad to work in the other room.
But when it comes to the real big picture, I use my specialist interest in football to guide me though the world of academics, the world of rock and roll etc, so I know all the cool and artistic sort of world there is out there, as well as having a good understanding of Irish and world history, knowledge of the Irish language etc.
An average fan in my position would be stuck on knowing about football, a few rebel songs and Republican 20th century politics, maybe a sprinkling of Republican history before that.
I think my advice for aspies who can't see beyond their specialist interest is to use the specialist interest to guide your knowledge on other things. To use a cliché example of a specialist interest (trainspotting), don't just learn about train routes but learn about the places to which they go, the invention of the train along the way, the lives of the people who invented new trains and the life of Stephenson, the life of the guys who invented the train before him, how trains are represented in the media etc etc…
And yes for my friends on here lol... look up the novel/movie Trainspotting...
