I have a friend who is doing this.
I have HFA. Very few people know because I mask a lot. People I know who work with people with autism often guess or suspect.
I've had a friend for about 7 years and I just wondered what you think is going on here because I don't understand why he is doing this.
He is increasingly using the language of autism to talk about himself. He doesn't believe he is autistic - he's told me that. But he is quite happy to let other people believe that he is.
Yesterday, he made an unpleasant comment about how "everyone else's 'isms'" are catered for but his are not. What actually happened was that we had plans for the evening; he tried to manipulate me into changing them; I just said, "I'm leaving at X time to go to Y place as we planned. Let me know if you want to come." He send a few "cheers mate
" type messages. I didn't engage and he did end up coming out with me but was a bit arsey and snippy until he got talking to someone who is autistic and spent the evening telling this guy how "amazing" and "awesome" he is.
