"I can't believe you still do stuff like this. Are you ever going to grow up?" "I still do it," Corey said. "Because you're a guy. Girls don't climb walls. Not real girls, anyway. Just tomboys whose closets are filled with tank tops and jeans and sneakers. Who still consider braids and ponytails high fashion. Who wouldn't know how to apply makeup on a dare." "Knock it off, Hayley," Daniel said. I was wearing makeup. Just not a lot. I had my hair down, too, and although I wearing jeans, they were my fancy ones, paired with a new fitted tee and ankle boots. It might have been the T-shirt slogan that she objected to--BRUNETTE IS THE NEW BLONDE--but I didn't buy it to set her off. "Am I the only one around here who thinks Maya has a hidden Y chromosome?" Hayley said. "If she does, she's hiding it pretty good," Corey said, giving me a lascivious once-over. Hayley scowled at me and opened her mouth to say something else. Daniel started to cut her off, but Corey beat him to it. "Lessons later," he said. "First, we need to see if this girl is as good a climber as she thinks she is. Challenge time. A race to the top. Maya versus anyone who dares take her on." "That'll be a short list," I said. Corey grinned. "Not when they hear the prize." He turned to the others. "Anyone who beats our Sweet Sixteen gets to kiss her. The lineup forms behind me." Brendan got behind him. Daniel grinned at me and joined. The other guys filed in. "Oh my God," I said. "What are you guys? Twelve?" "No," Brendan said. "Just really, really immature."
