Planes and alarms and nobody cares

I woke up at about 11am today. Military airplanes flying far too low for my liking were circling what seemed to be my apartment for a few minutes. Then the alarm goes off. Not my alarm clock but the alarm that is probably in every neighbourhood of every city and town in Korea. The alarm that sounds like the four minute warning you hear in those films about World War II or when their is a nuclear strike. Of course, nothing happened. The alarm goes off many times (tests or drills) and no Korean here ever bats an eyelid despite the tension on the peninsula. And neither do I but it's something I won't miss when I go back home.
