Leaving the US to visit your parents in Korea, you dozed off comfortably in an airport seat. Suddenly, the PA system blared your name, along with another person's, calling you to gate nine at terminal three immediately.

Startled, you grabbed your backpack and dashed off from gate 5, realizing it was still a long way to go. As you ran, another guy, also late for the flight, caught up with you, panting.

"You too?" he shouted, running alongside with his luggage.
