Translation of charade in German

Probably we will make additions to our dictionary. I'll be available in January and in February, but not in March, because I'll be in the United States for about three months. About a week in New York, a week in Chicago and Detroit.
I've never been to Switzerland, but I've been thinking about visiting it for a long time. Until now I was only in France and Holland. I should take the time and travel and visit new places.
Of course I understand the reasons. I live in Thun, which is not far from Bern, our capital city. How come your Spanish is so good? Have you ever been to Switzerland. You are most welcome.
