I'm standing in a store with a 15-year-old young man diagnosed with Autism. We are an unlikely gang of four: me, another clinician, his mother, and Joseph. Joe towers over my 5'1'' frame, and he's twice my weight. He looks pretty intimidating. Before entering the store, I removed all of my jewelry, took off my eyeglasses, and stored any items in my hands... I'm ready for action... It's about to go down!
