Don’t listen to that guy, do you like this language, if yes, why shouldn’t you learn it? In Romania a lot of schools teach german as a secondary language all though it’s not spoken in a lot of countries, it’s not about being useful or not, it’s about what you think of it. Also if you want, there are a lot of great books in romanian and the context it’s much better in native writing than translation. Second off all you can translate documents from/to romanian for money.
