Have you ever had a nickname that referred to something embarrassing you had done? Maybe "Booger" because you got caught picking your nose. Or how about "Stinky" if you aren't the best housekeeper on the planet. Do you like being referred to based on things that are not your best qualities? Is that all you want people to see when they look at you? Is it even the first thing you want people to see when they look at you? Probably not. So why would you assume that it's okay to see autism when you look at a child who happens to have it?
Read some of these letters from people who have autism. Though some may find it difficult to deal with and focus on autism, some of them have been able to do what people who don't have autism have difficulty doing. While those of us are constantly seeking ways to "help" those with autism or "find a cure", some people with autism don't want this help and truly wish that others would just leave them alone. They don't view the autism as a problem, just something that is a part of them, much like some of your behaviors are part of you.
It's important to remember that the behaviors do not make the person. Too often people are judged on their behavior, though others may have no idea what caused the behavior. Use some of the tips below to help you to see the child instead of the autism.
