I was never diagnosed with autism. Everyone just assumed I had autism by my appearance. Never mind that I routinely scored the annual evaluations on the genius side ("statistical flukes"), had a college-level reading comprehension after eight years in Special Ed classes (school officials couldn't call that a "statistical fluke"), and skipped high school to go to community college.
Um, autism is not the same thing as Mongolism (having Down's Syndrome). My uncle had Down's Syndrome; such individuals have physical attributes associated with the syndrome (such as almond-shaped eyes and large tongues). Autism is a mental condition where there is (usually) nothing wrong physically, but their brain is wired differently. I have an autistic nephew.
