I'm not an adult, luckily and unluckily. I do feel as some people treat me too sensitive sometimes. I also feel as others are just, distant towards me. My mother, who does not have a neurological disorder, says people treated her like that as well. She used to be shy, so everyone thought she was snotty. Anyway, one of my teachers wanted to yell at some people who disliked me (not for disliking me, for other issues) He let them go. He said, "I won't do anything, being stupid is their punishment." A little harsh, but he does have a point.
As for adults, I met adults who aren't on the spectrum and act childish. In return, they're treated like children. Everyone in the real world is treated how they act.. I've also met people who I assume are on the spectrum and they're treated like how they act, so either childish or quite mature. I have met many mature autistic people, I think the antisocialness adds to it. Well, this is just my uneducated take on it.
