Lindbergh Elementary School

Earlier that Day

"This is weird," Libby muttered under her breath as she entered Ms. Fowl's classroom.

"What is?" Sheen asked as he jumped into the seat next to Libby. He put his feet up on the desk as Ms. Fowl exited the classroom and walked down the hallway.

Libby sighed, but she couldn't help but smile as her neurotic 'boyfriend' sat next to her. "Cindy and Jimmy aren't here yet. They're never late or absent. They live to compete with each other here."

Sheen shrugged. "Everybody gets sick, Libs."

Libby shook her head. "We just saw them yesterday. They looked fine."

Sheen thought for a moment as Carl took a seat next to him. "So do you think that Cindy has invited Jimmy to play hooky with her in an elaborate attempt to get closer to him, thereby excluding us?" he offered. Sheen stopped talking and rubbed his chin. "Nah, that's stupid."

At any rate, the three friends shrugged off this strange phenomenon and turned their attention to the blackboard as Ms. Fowl reentered the classroom.

Several hours later the three friends made their way to the cafeteria. A little confused about where to sit since Jimmy and Cindy weren't there, they took a seat with Nick and several other classmates.

"So, this is really weird, guys. Jimmy and Cindy are still out," Libby mentioned once again.

Sheen just kept eating. "Libby, I really don't see why you're so upset. This is all that is happening. Jimmy and Cindy are both sick. It's not that weird."

"Yeah, I guess you're right," Libby told him. Wow. That's definitely not something you usually say to Sheen.

"Why don't we just visit them and make sure they're ok after school?" Carl offered.

Libby nodded her head. "Yeah. Sheen's right, they're probably just sick. I'm sure they could use the company."

Just then the bell rang. All children in the cafeteria sighed as they gave up their twenty minutes of freedom and returned to the prison that was their classroom. Carl, Sheen, and Libby tossed their trays into the garbage. They continued talking as they began the trek back to Ms. Fowl's class.

"Hey, check that out!" Sheen shouted, interrupting Libby and Carl's conversation. The three of them stopped walking and looked behind them. Several men dressed in black carrying packages entered the school and headed towards the office.

"Who do you think they are?" Carl nervously asked.

Libby looked outside the window. "Just some package delivery people," she answered while looking at their truck.

"Move it!" an angry fourth-grader shouted. Sheen, Carl, and Libby were obstructing the flow of traffic in the hallway.

"Come on, let's get back to class before we're late," Libby told her friends while glaring at the fourth-grader. They continued down the hallway.
