Translation of thong in Spanish

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.
I have began to learn English. I like to swim and to dive, because I lived near the beach while I lived in Miami. It is not similar to any other sport. But this week have not been yet to the pool.
Which region in Germany are you from? I live in Aarau in the state of Argau, that is in the middle of Switzerland not far from Zurich, Lake Zurich and near the border city of Basel.
