Mrs Kim's brother, a university professor in Seoul, was the founder of
Best Language Institute,
and Mrs Kim was the institute's director when Margaret taught there. She sold the
hagwon in September of 2010.|
Margaret stayed with Mrs Kim for three months at the beginning of her year in Korea.
Notice how I always say "Mrs Kim"? There's a reason for that. Unless you're really close friends (as in lifelong friends) with a Korean, that's what you do. Though it may seem a little odd to call them Mr and Mrs, those English titles seem to be pretty widely accepted.
BTW, you'd normally call your hagwon director won jang nim. But don't assume - Mrs Kim liked "boss." No kidding.
