Izzy was still thinking. “Okay,” she said, after a moment. “Then what’s your most embarrassing story? The most completely embarrassing thing you ever did, or that ever happened to you?”

“What?” Emma said. She hadn’t been listening, had become a little distracted by her own thoughts.

Izzy smiled smugly, as if she knew exactly why Emma had been distracted. “Your most embarrassing story,” she said. “What is it?”

“Oh,” Emma said. “I don’t know.”

Izzy smiled some more, and now her smile was definitely teasing. “So think of one,” she said. “And tell me. Because this is all your idea.”

“Think of one?” Emma said still a little confused.

“A story,” Izzy said patiently. “That’s embarrassing.”

“Oh, yeah,” Emma said, then just sat there looking at Izzy. She had no idea what to say.

“So what is it?” Izzy said, after a moment.

Emma made herself think.
