We know he experiences many autistic traits such as echolalia, but unfortunately he repeats the things we don't want others to hear that might have been spoken out of frustration. It is very frustrating trying to learn what is the matter with him when he is upset because the echolalia manifests itself predominately when he is stressed.
Coincidentally I am trying to get my daughter who has asperger syndrome to practice echolalia to show people she is listening to their conversation without having to work so hard at it. Opposite of her brother, she is quite frustrated with not being able to speak her mind even when it is extremely off topic. I am amazed how different the two people and conditions are.
So I use echolalia to come up with a means for writing on tasks regarding a subject at hand, and I regret not coming up with my own thoughts immediately and having to write what I think others want to hear. As I tell most of my friends who know our family, the apple doesn't fall far from the tree nor does it care!
All kidding aside if your reading this I promise to bring some originality and and my own experiences to this blog as I travel a road living with autism.
