While discussing our pending Germany trip:

Amber: Guten abend!
Me: It's not "guten nacht"?
Amber: Close, "nacht" is only for when you're really going to bed. And it's "gute".
Me: Ahh "gute nacht".
Amber: Yup. (Surprised) How did you know the word for "night"? Are you listening to tapes too?
Me: No, uh, "Kristallnacht" was this horrific event in Jewish German history where there was a concerted effort by Goebbels to terrorize and imprison thousands of Jews. It translates to "Crystal Night" in reference to the windows being smashed of shops and the mayhem in general.
Amber: Oh...

Me: Sorry. All the German I know comes from the History Channel and beer labels.
