High School Boys and the New Term
The discussion among the group of four ends when they hear her footsteps. The teacher walks into class and greets her students. Turning to the board, she begins to write on it and tells them there was something about which she'd tried and failed to contact them. She turns back to reveal a message on the board, which reads that it was still winter break and that school would start only the next day.

The teacher runs out of class laughing, while the furious boys give chase. The end scene shows her escaping from them by hiding behind a wall.
