There was a brittle tap, tap, tap on the glass pane of the classroom door. The magical mood was broken.

“Boo! Hiss,” Vivian Kim muttered. “Yes? Who's there? Hello? Who is it?” she called.

The glass and polished mahogany door slowly opened. One of the kids hummed from the score of on Elm Street. Mr. Soneji, hesitantly, almost shyly, stepped inside. Nearly every child's face in the classroom brightened instantly. “Anybody home?” Mr. Soneji piped in a thin squeaky voice. The children erupted with laughter. “Ohhh! Look. Everybody's home,” he said.

Gary Soneji taught mathematics, and also computer science-which was even more popular than Vivian Kim's class. He was balding, with a droopy mustache, and English schoolboy glasses. He didn't look like a matinee idol, but he was one at the school. In addition to being an inspired teacher, Mr. Soneji was the grand master of Nintendo video games.

His popularity, and the fact that he was a computer wizard, had earned him the nickname “Mr. Chips.”

Mr. Soneji greeted a couple of the students by name as he quickly made his way to Ms. Kim's desk.

The two teachers then spoke privately at the front desk. Ms. Kim had her back to the class. She was nodding a lot, not saying much. She seemed tiny standing next to Mr. Soneji, who was over six feet tall. Finally, Ms. Kim turned to the children. “Maggie Rose and Michael Goldberg? Could the two of you please come up front? Bring your things if you would. ”

Maggie Rose and Michael exchanged puzzled glances. What was this all about? They gathered their belongings, and then headed to the front to find out. The other kids had begun whispering, even talking out loud in the classroom.

“Okay. Put a lock on it. This isn't recess,” Ms. Kim quieted them. “This is still class. Please have some respect for the rules we've all agreed to live by here.”
