I don't know the language at all! I'm visiting my sister, who moved in Germany three months ago. She didn't know the language at all and was pretty dependent on her husband. Now she manages in basic things.

It was hilarious when in store I asked if the saleswoman knew any English and the sale personnel were like, "Oh no! Who speaks english?! you! you speak at lest some! Take her!", in German, and they didn't understand that of course I could *guess* from their body language what they were approximately saying ;)
