I was in the US embassy this morning. A bunch of Korean girls (5 of them) were sitting in front of me. They are about mid 20's to early 30's I think.
Not only that, they were so soft spoken and well-mannered. Each time, when one of their number is called, they will politely excuse themselves with a little bow and nod of head to the read. When they laugh, they will shyly covered their mouth. Sigh, such delicate creatures.
