My first CouchSurfer (May 2012) came from Lithuania, and his German was very good, so we played a session of Language Hunting in his original language. We pretty quickly moved from two cups to “want/have/give/take”, and I learned to know that Lithuanian always changes the ending of words. It’s supposed to be a pretty complicated language, and is something like a model of ur-Indo-European for linguists, so I’d loved to do more of it, but anyway it was a nice glimpse. tä tuščas puodelis!
