It's as good a guess as any. IMHO, nobody's got any answers. My own guess is that this is revenge for something that the South did, but we may never know what. A lot of South Korean shit goes unannounced by both sides because the South doesn't want to appear as an aggressor and the North doesn't want to admit it's been hit. A veteran sea captain who sees credit for a successful attack going to some punk kid would not be a happy camper, and his friends and service buddies wouldn't feel too good about it either. Which is why I don't really buy into this "take your kid to work" explanation. Still, nobody knows.
