Some days before, I decided to leave my bike at home and take the bus instead. On the bus, I pull my cap off. When I reached my stop, I got off the bus. While cross the street, I realized something were missing. My cap! I turned around, running to the bus, and the bus pulled away from the stop. Just then, a bus stopped a short distance away because a red light. While I sadly looked at the bus, the door was opened. A man stood near the door and looked around. Seen me, he waved something: It was my cap. I barely had time to grab them and say thank you before the door closed again.
