For listening, Čeština is definitely more difficult than Русский. :/
Even after I study the dialogue, when I listen to the recording again I go “Eh???”
I’m starting in a new job and one of my coworkers is from the Czech Republic. So of course I’m starting to learn Czech.
You could say it is crazy, considering I’m still a beginner in Slovak and I haven’t even broken through the intermediate level in Russian. But I say it would be even crazier to miss the opportunity to learn and practice a language with a native speaker. 🙂
