Brenda: Low functioning autistics have no language skills; they cannot survive independently by themselvles. Keith is not like that. According to his school records, he's very intelligent but he does have issues : he's unemotional, frequently says inappropriate things, he's literal-minded, he gets fixated on minor details, he gets agitated when his routine is altered and he's extremely uncooperative when anything or anyone gets in the way of him doing what he wants.
