Teasing: Best Friend

Just after the bell rang, someone noticed a sticky note attached to the underside of their desk. The person grabbed it, looked at it, then read it. "I wish that the person sitting to the right of me would become my best friend."

But then the person shrugged and tore up the note, essentially destroying it. As the teacher began to talk, however, something odd began to happen. But who read the note ... and who was sitting to the right?
