Teaching English

CULTURE SHOCK
When first arriving in a country, one is usually excited and eager for new experiences. After a while, the newness wears off, and homesickness begins. Do not judge yourself too severely at this point. It happens to everyone. "I will never understand this place. I want some real food, some real friends, a real apartment. Why do Koreans do X?"
There is hope and it is usually just a matter of time. As you continue to cope with the realities of living here, you begin to take things for granted which used to annoy you. Life becomes pleasant enough that you no longer care about the inconveniences. You suddenly find that you like kimchi. You realize your students are interesting people to know, that helping them improve their English just adds to that interest; you begin to understand your boss who was such a pain when you came; you make a few good friends who are willing to show you the Korea outside of the foreigner's community, you begin to try and learn some Korean and use it. There are many foreigners in Korea who have come to and remain at this point, - not so much assimilated, but a part of the country in their own niche here, and who want to spend a long time in Korea.
For many others, however, the feeling eventually comes that it is time to leave. With luck you will realize it before it affects your life too deeply. It is time to leave when you begin to be negative about the country and its people. When you no longer want to go to work; when you dislike your students; when you become irritated with everything and everyone and have angry discussions with others of like mind, it is time to go.
