Sadie came to our house every day after school, and I watched the Snickers incident play out over and over, in different forms, with different objects. Shawn would ask for a glass of water. When Sadie brought it, he’d want ice. When she brought that he’d ask for milk, then water again, ice, no ice, then juice. This could go on for thirty minutes before, in a final test, he would ask for something we didn’t have. Then Sadie would drive to town to buy it—vanilla ice cream, fries, a burrito—only to have him demand something else the moment she got back. The nights they went out, I was grateful.
