I learned from one of my friends that there was someone in our year at secondary school who was autistic, but my friend didn't know if it was Autsim or AS, don't think he spoke to him that often. I never knew him at all, although he was in some of my classes. I always wondered why he was so quiet though (it wasn't until I started sixth form college that I suspected I has AS, before then I knew nothing about ASDs).
I've finished my first year at sixth form, and all through the first year I knew someone in the second year, and when he was in his first year, it was thought that he had AS. But he went to doctors, etc, about it, and he wasn't DX'd. The only traits he had were obsessive interests and formal, pedantic speech. He has no communication and socialising problems whatsoever, or any of the other traits.
We got along with each other so well, and when I told him that I was waiting for a DX, he told me that it was thought that he had it, etc, and from then on I got really close to him. He was really understanding of me, and he was the only person I could happily talk to about my interests. My other few friends I have aren't easy to talk to, just like any other people. I can't talk to them about my interests, I just don't know how with them!
