Remember The person with autism is first of all a real person.
Treat the person the way you would like to be treated.
Considerations when interacting with people with autism
Be aware that sometimes people with autism make noises that are unusual. Generally, they can’t help it. It is best to just carry on without drawing attention. Also, people with autism often have “self-stimulatory” behaviors; such as: jumping, flapping, and particular eye movements. They are just part of autism, and it is kind to not make a big deal about them.

It’s ok to ask a friend about his or her disability, but it’s also okay for a friend to not want to talk about it. It should be the person’s choice.
