At the barbecue, my sister said, “Your son will always need help”—and then she started laughing… My name is Julia Baker, I’m 42 years old, a software developer and single mother, and I live in a quiet suburban neighborhood. Suddenly, the barbecue sauce on my plate looked like blood. I looked up and saw my sister, Amanda. She was holding a glass of wine and smiling as if she had just told the best joke in the world. But it wasn’t a joke. We were sitting at the long picnic table in my parents’ backyard on Labor Day. Everyone was there. My 15-year-old son, Alex, was sitting next to me. He was staring at his paper plate, trying to become invisible. Amanda pointed her fork directly at him. Her voice was loud enough for the neighbors to hear. “Oh, come on, Julia,” she said, making a dismissive gesture with her hand. “Let’s be realistic. Alex will always be special. He has limitations.”
