Well, in reading this discussion board, it appears that I am quite unique in having more Korean than foreign friends haha.
The reason I chose Korea as a country to teach English was largely because of the many Korean friends I had made whilst volunteering in an international voluntary community in England. There number of Korean coworkers far outnumbered any other nationality, so quite naturally a large proportion of my friendsships made were with Koreans.
Since coming over here my weekends have been spent travelling the length and breadth of the country to visit as many of my Korean friends as possible - and what a great way it has been to see the country, get special insights into the culture, and to experience their way of life first hand. I have been lucky enough to have been invited to the Chuseok and Lunar New Year celebrations by some of my friend's families, and seeing the preparation that goes into such celebrations has given me a new-found respect for their culture, and a reminder of the importance of tradition in celebrations.
I live in a location which has made it extremely difficult for me to meet foreigners on a regular basis, but at the same time this has provided me with the "total immersion" experience that another poster commented on. It has been challenging at times, but on the whole I am happy with my situation because it has taught me a lot more about the Korean way of life than I otherwise might have learned.
I have recently started taking Korean lessons, so I can't wait to see my Korean friends' reactions when I start speaking Hanguel to them! I think it is respectful to make this effort, and I'm slightly embarrassed that I haven't been able to do so sooner.
Having said all this, it would be great to have some more foreign friends to create that all important balance!
