So you have taken a German course in the Ghoete Institute. Well, I certainly learned something with you, and your German is already a lot better than last time. I think we really did it.
It is good if you have previously practiced only Spanish, which also shows that you are very good at other languages, and still can learn many things. I hope I'll learn it soon and practice.
Have you ever visited the U.S. before and if so, where have you been in the U.S.? I've been travelling in California, it was very amazing. We have traveled by car. Here are my corrections.
