This is my special runway walk,” Suzanne Lock told the group of girls that were gathered around her on the playground after lunch. She lifted her head high, straightened her back, and took long strides across the yard. Katie rolled her eyes. Her best friend was showing off . . . again. “It’s very important for a model to have her own special walk when she is modeling clothes,” Suzanne explained. “A model has to stand out. At least a supermodel does. And that’s what I’m going to be.” “More like a supermoron,” George Brennan shouted as he and his best friend, Kevin Camilleri, tossed a football back and forth. Kevin laughed. “And Suzanne won’t have to practice for that,” he said. “She’s already an expert.” He lifted his nose in the air, sucked in his cheeks, and imitated the way Suzanne was walking. “Oh, that’s beautiful,” George told him, pretending to take Kevin’s picture with an imaginary camera. “Smile for the camera!” Suzanne stuck her tongue out at the boys.
