Beep, beep, beep, beep. The warning sound and flashing lights alerted commuters that the train door was about to close. Yet a few tardy individuals still made a frenzied scramble across the platform and onto the train. The door closed on one of them. Thankfully, it rebounded and the passenger boarded the train safely. I wondered why people took such risks when the next train would arrive in a mere 4 minutes.
