I see there is yet another interesting story about an autistic kid in a cage. Along with "retard", calling the special education bus a "tard cart", "look there's a kid in a cage" is yet another cliched insult among those who bully autistic children who attend special schools. I have previously written about my personal experiences with this slight going back to my childhood in the 1960s. I also used this line in my short story, Mr. Twiddle which I wrote quite a few years ago. Also used this line in my unpublished novel "The School of Hard Knocks".
Stories about autistic or other developmentally disabled kids in a cage fascinate me.
