Translation of federnd in German-English

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.
I will be creating an additional study with a student (his name is Juan), which may appear in local newspapers in the future (in English). However, this may take a couple of weeks too.
Why do I never travel? This is a very good question, but I do not know how to answer it: On one hand, I like the landscape, but on the other hand it annoys me to pack and to drive or fly.
