"Guten Tag, wie geht's?"
"Fine, und Ihnen?"
"Sehr gut, danke!"
"Where did you learn German? That's amazing!"
Rowing at the UCSB.
I took the examination as well and the examining professor knew that I was from Germany and said "endlich..." when I entered the room for the exam. There was another professor from the English department who grew up in Germany, so we chatted a bit in German before starting the actual exam. And afterwards we talked about rowing ;-) I just really hope I passed!
So far, I have not met many German people. There are also two post-docs at the Mechanical Engineering faculty I ran into, but that's basically it.
