Hey guys...my question is pretty simple to ask, but a little hard to define. What do you consider the meaning of being fluent or being bilingual?

I have been living in Honduras the last 6 months and speak spanish pretty well. Some of my friends tell me I'm fluent because I can understand and speak the language. However, I don't feel fluent. There's still so much I have to learn, and certain words I don't know yet. My skill level is that I can understand everything when I'm having a one-on-one conversation, and I understand most everything when there's a group of people. I can also speak the language very well, but still mix up some conjugations and stuff every once in a while.

My friends also call me bilingual because I converse and use spanish just as much as I use English on a day-to-day basis. Others tend to say I'm a lot farther than how I feel I am.

So what do you consider being fluent or bilingual means?
