In September I'm going to Germany for a week for work. There's a big trade show that fills something like 100 buildings and lasts a week.
Yet, I'm still somewhat apprehensive. See, I don't speak German. My Spanish is pretty good, and I can speak English well enough. All my travel thus far has been either to a country where I spoke the language (domestic, Spain, Ecuador) or with someone else who did (France). While I know that the conventional wisdom says that everyone in Germany speaks English* I just like the idea of at least being able to say "please", "thank you" and "excuse me".
While I thought about taking classes, I've been in airplanes enough lately to read thousands of advertisements for Rosetta Stone's language software. So I picked up the "German Level 1" set to try out and see how it works. After doing the "Day 1, Lesson 1" set, I can conclusively say that I know how to say "a boy is under the airplane" in German.
Obviously, this will come in very handy in the event a kid gets lost at the airport and starts running around the tarmac while my flight to Germany is taxiing.
* Indeed, every German foreign exchange student we had in high school spoke better English than most of the other kids in the class.
