Translation of retention 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.
Yes, my Spanish is much better than your German, but it is not true that I do not want to learn with you. I think this is not an issue. Where do you come from in the U.S.? East or West coast?
Great that you've written me back so quickly. I want to be your pen pal and we could help each other. I am looking for people who could help me learn Spanish, with focus on conversations.
