One of my housemates' kids has Asperberg's. He's eight, and he gets it when someone tells him STOP. He understands boundaries. Okay, sometimes he'll try to push them, but he is, as I said, eight. I never knew much about Asperberg's until I met this kid, but now that I know and love him, I get so annoyed when I see people, both in real life and fiction, blaming their bad behavior on Asperberger's.
