I have a friend online who is Korean (North? South? Don't know,
  don't care, didn't ask). He started following me on Google+
  after I made some quantum physics posting and he had something
  to say about it. [he's studying Quantum mechanics at his
  university). anyway, he only writes in Korean. I only write in
  English. Google translate's Korean is laughably horrible but
  it's enough for us to have conversations about everything.
  Science, to girlfriend trouble he was having, to depression he
  was going through, etc.
