Circles
On a community website where I spend a lot of time, someone asked recently for advice on how to deal with his noisy neighbours. He doesn't live in Korea, but he thought that the couple next door was Korean, and that when they were shouting at each other in the wee hours, they weren't shouting in English. He reasonably took this as an indication that some knowledge of their cultural background could come in handy if he girded his loins enough to talk to them about it. I responded:
Koreans are fighters, certainly, but no more than anyone else, I don't think, and it's not like it's a cherished part of Korean culture or anything. What is a part of Korean culture is to ignore people who are outside your circle of personal friends/acquaintances/family. If someone's not in your circle, they are an unperson, so a) their feelings are not considered b) you can be unembarrassed about airing your dirty laundry, in whatever form.So if these folks are indeed Korean, making friendly overtures so that you impinge on their humanradar (depending on how old-skool Korean they are (ie if they hew fairly closely to the usual Korea-Korean norms, it'll work)) might just make you a person to them, in which case they'll be too ashamed to make all that noise.
Most people who come to Korea to teach, whether at a hakwon (the catch-all term for the private-study schools that can be found literally 10 to a city block, catering to the monomania not for quality but quantity of education here in Korea, many of which specialize in English and employ most of the short-termers in Korea), or a university or foreign school, or in-house at a company, or somewhere else entirely... most of them are provided with housing.
