Another passenger approaches, a tall young man, grad student type, and he and the man of the couple recognize each other. They greet each other in English and then switch to fluent German. This goes on for several minutes. The German man leaves. The young Chinese couple resume conversation, but this time in flawless, unaccented English. The man explains to the woman, "That's the guy who. . . ."
Confusing to us poor monoglots.
