All I know is that autistic people seem to have a pattern of speaking, listening, etc. It is important to wait to speak until they are ready to listen. How does one know this? I have no idea, but I can often tell. I know I unconsciously copy people's speech patterns, and that seems to help? I've talked to many autistic people who I never dreamed were autistic. I was told this by a doctor, and the whole concept surprised me a lot. But there seems to be some truth in it?
