What kind of music do you like? I am a classical music and rock fan, but not a techno fan. I believe that strange combination of tastes say a lot about a person. I certainly want to take art as a major.
I speak a little English. I would be happy to teach you German as well. May I can introduce myself? My name is Jürgen and I live in Dusseldorf. 25 years ago I was born in Mannheim, Germany.
