I noticed that Korean Parents' apartment has an ant problem the other day - even though it's on the 13th floor, but Korean Mother isn't really bothered, because they don't do any harm and it seems that in Korea having ants is seen as a sign of wealth, so bizarrely, I think she's almost proud that they've moved in.
They are however, brown ants. Apparently had they been white ones, this would have been a very bad thing. Not another subtle manifestation of Korean pride though as it turns out - it's simply that the white ants eat into the structure of the buildings they infest. White people merely eat into the structure of Korean society, which is perhaps a less tangible thing to complain about, although the Chosun Ilbo does try quite hard.
