i think it's not too bad as I'm still in thee beginner levels
and let me ask you about your opinion,
what do you think about Russian language as it's a mother tongue for you!

I think Russian is a great language, which still keep some Old Greek nature.

In fact, I like Russian because of the Russian song named Катюша in Russian, the folk song you must know.

Yeah, there are many difficulties learning Russian, such as the pronuncition of 'р', and some of word like 'песню' and 'степного' and the like, but in the other hand, it's funny, isn't it?

I'd love to learn russian, but I think it's hard a little bit.
