Excerpt:
"Karla’s cousin Jade urged her to join the step team. “This afternoon you should definitely try out!” Jade suggested after the final bell rang.
“I know she wants the best for me,” Karla thought to herself, “but I’m not sure I’d be any good, and I’d feel embarrassed if I messed up in front of others.” Karla had seen step teams in action: they stomped, they clapped, and they performed all kinds of skillful, synchronized moves. "
