I heard that except for a very few " enlightened " koreans, the atmosphere is mostly tense with nary a word or two for long long sector period. Conversation is sometimes non existent and most of the time if a conversation goes on, it ended up without anyone none the wiser as most of the Koreans have poor conversational English. Having said that, there are a few western trained Korean gentlemen who speaks better English than the expat Latinos and aussie with their dreadful drawl.
