Translation of Trübung

I would like to know if Jack is interested to join us as well. Shared learning is called Tandem. I'm coming in 2 days to Spain. I will pay for the study costs of my daughter, and I assume all other costs as well.
Once you've put it online, I'd like to check the text for eventual inconsistencies. Let me know how it goes. So that I can review it as well. Let us be in touch towards our next study session. I will be there on Wednesday.
Perhaps we are could meet sometime in person, not just via the Internet. Of course, we should still write each other a lot. I will get back to you once I am back in Cologne, and then give you know.
