Wow three languages fluently that's awesome. How did you get to learn and understand all of this to even consider adding a fourth?
Well, English for me. Also have a native language but wouldn't include it has I'm so poor when it comes to speaking and understanding it. Due to were I grew up, u could learn much of it.
Would love to learn several other languages. French and Spanish seems like a very good. I know in time, I will have to get acquainted with one of this.
