Ich habe Deutsch für ungefähr fünf Jahren im Hauptschule und an die Uni studiert, and the one thing that I always remember is that in our last semester of German IV senior year in high school, there was no English allowed in the classroom. I'd go to my next class, and sometimes folks would look at me funny and be like "dude, stop speaking German!" I literally had no idea; it was like there was a subconscious switch that flipped in my head, and I was just talking. In the wrong language.You joke, but I actually noticed that I started using some German ways of speaking English when I first came back. The adjustment back to real Navy life has been interesting.
