Once upon a time, a man named Steven cleaned dirty train seats in London. He found so much black yuck from just a few seats! 🚂💺🧼 Steven showed everyone how dirty the trains could be. People watched a video of him cleaning and were surprised. 🤢 He talked to the train people, and they have a special way of making the trains all tidy again. And that’s the moral to the story.
