That's what happened to Neil and my Mom. Neil is my 5 year old autistic brother and we live in Wichita, Kansas.
Autism is a disorder in which most cases it is hard for autistic children to do the simplest tasks.
They can't understand things as quick as you and I can. My brother Neil goes on a bus to his school daily. His bus driver, Jeff, and my mom work very hard on trying to make him wave appropriately, but he never would do it by himself. Oh, he'll wave someday soon. Off the bus he went.
