Hi Femme, I’m going to answer as myself but please know that this is only my experience. There are so many different ways that autistic people present so what I’ve experienced will likely not be what your sons future will be.
i grew up on a council estate and there were kids everywhere. It was the done thing after tea to go out and play. I did play so I had neighbourhood friends. However, I felt much much happier being at home reading (I had a LOT of books).
I had school friends so I did have people to play with at playtime. I didn’t have a ‘best’ friend though. At secondary school I had a small group of friends and we hung out at weekends either as a group or 1:1 at our homes.
it was around early 20’s when I really became aware that I was no longer in a social circle of my own and that I wasn’t sought out.
today, I have no-one I would call a friend. I have neighbours, local shop keepers and people from my dance class that I briefly chat to but nothing beyond that.
however, I am really so happy that the world is becoming more neuroinclusive and awareness of neurodivergence is growing. That means the future for your sons will likely not have the same social struggles I’ve had. Also, I do feel hopeful that my diagnosis means that I now might find ‘my tribe’
in my work is where I’ve had the most challenges - people find me intense and focused and find me disconcerting because I hate waffle and flowery language and am not very interested in talking beyond the briefest social basics. I’ve had quite a few managers who have used very negative words to describe me, however I have had managers who are much more inclusive and have embraced the skills that I bring. I have been very successful despite all the challenges and this is because I am focused - once I know what I want, nothing will stop me from achieving it. I earn a six figure salary. Again, I’m happy that my work are doing a big push to make the workplace more inclusive so I feel cautiously optimistic that I won’t continue to be negatively impacted.
long reply - I hope I’ve answered your question.
