Unfortunately, society sees autism as a serious disability because it is expected that a fully functioning person can behave in very narrow, circumscribed ways. It is time to inject fresh ideas and put old tired ideas to rest. Ignorance and a lack of technology held us autistic people hostage in the past. Ignorance and prejudice still hold too many of us in that silent abyss. I think autism has good and bad results.
Autistic people can remember large amounts of information.
This is good, but we also remember all the sadness, too. I would tell the parents that they love them. Also get them swings, balls, and classical music to listen, too. Never give up hope. I would not be as calm without massages and pressure to my body.
