This is about NOTHING but all the Chinese I remember.
I did have a Korean army doctor as a roommate for 9 months so I picked up a small amount of Korean but not much. This was while I was a third year law student on the graduate student floor of a very large dorm on the U of MN campus-- Middlebrook Hall.
It is bigger than it was in 1987-1989.
