"A middle-aged woman with brown hair pulled back into a neat bun, wearing a navy blazer and khaki pencil skirt, is standing at the entrance of a brightly lit classroom. There are colorful posters on the whitewashed walls and wooden desks arranged in rows. She is gesturing for a group of teenagers who are sitting at the desks, chatting and laughing, to follow her out of the room."
