I soon learned that the best way to be listened to was to talk about real things but make them exciting. To talk about the endings I wanted rather than the reality of life. It was a poor substitute for fantasy but it got me listened to and made me feel important in the eyes of my parents.
Of course, I went too far in those early days and I can remember trying to convince my mother that a haunted house (which I got too scared/lost in and had to return out the entrance) was full of huge obstacles. I think I lost her when I mentioned the pool of sharks.
I also found it difficult to talk about other people. I'd be at school and I'd see something interesting which I'd want to talk about. Those early days were all about "who was it?", "oh, is he a friend?", "do you play with him at lunchtime?" and a thousand other unrelated questions. I wanted to talk about whatever fascinated me, not spend ages explaining who someone was and then answering "twenty-questions".
I soon learned to claim incidents as my own. To talk about things from the first person and to not mention other people. To me, these weren't lies, they were just suppressing things that I didn't want to discuss. Of course, my parents considered me a liar.
I got better though, much much better and after a while I was able to not only talk about things that happened as if they'd happened to me but also to "reprogram" myself to remember them that way. I became so convincing that I convinced myself.
Things came to a head one day at school when my parents and other teachers started acting on things that I said. Those embellished stories were having an effect in the real world and hurting people around me. I had talked to my parents about a "crazy" teacher and related some things in the first person. He got into a lot of trouble and eventually left the school**. I didn't mean for anything bad to happen but it did simply because people were listening to me and I resolved never to lie again.
It's hard to know exactly how much of this was Asperger's syndrome and how much was just me being myself. Certainly the clarity of memory and the ability to adjust memory seems to be an "aspie" trait. The struggle to be listened to is also a common thing amongst kids with Asperger's syndrome. I know that my own eyes glaze over and I don't give my own kids proper attention when they start talking about minecraft.
Sometimes I think we parents need to accept what we can from our kids - even if it's "garbage fantasy talk" but it's much easier said than done.
** BTW: As an adult now, I don't have any feelings of guilt over what happened to that particular teacher. He was really a bad person who did massive damage to other kids and he deserved to lose his job. It's just a shame that he didn't lose it because of the kids he was hurting. I know their lives improved drastically once he was removed from the picture.
