True. It doesn't have to be everyone at work.
I think that was the mistake I did in one of my previous work. I opened up during the orientiation of the team. Months later, had a discussion about autism with a team member because his eldest brother is autistic too, and he shared to me how he thinks autism is just an excuse and a figment of our imagination. Which of course I got insulted as well.
You are right, we still need to mask, and we don't need to tell everyone.
