I am going from London to Plymouth on a train. Iʼm sitting next to my friend John. Two old ladies are sitting opposite us. My travel bag is in the rack above my head. John has his suitcase under his seat. There's a table between our seats and the old ladies' seats. There's a puppy under the table. A ticket-inspektor is coming down the train. Oh no! Where's my ticket?
