Hey Xochi,
Thanks for your concern. Hmm, its interesting to say the least. NK have been threatening, for the last few weeks. Initially I was pretty concerned, but my Korean friends and co-workers don't seem that bothered. They even laugh it off and say that the news, that's reported in the west, seems to elaborate on the circumstances to make them look more terrifying than they are.
Obviously with NK now 'entering a state of war' with the South, my korean friends opinions may change, but so far, everything here seems calm. But i have my credit card, passport and a spare pair of underpants handy if i need to make a getaway.
