Holy Heaven! That's quite a few! Well, congratulations, that's really something! I only speak four 😛
And yes, Hungarian is difficult, I admit. You know, people used to ask me if Hungarian is difficult to learn. I'm always replying: "Not for me" 😁
But I'm tutoring my niece and nephew in English and sometimes it's difficult to explain certain words or sentence structures and always have to give them examples in Romanian to understand.
Can't see myself learning Japanese or Chinese, although I love languages.
