does it means anything?? or is it that she dunwan me to nkow? or im just being sensitive???
Yeah, it means exactly what she said, "Mind your own business." You
heard she likes someone else, didn't you? So you can't
possibly interpret it as a sign that she likes
you.
Although, if she is still in her teens (and she probably is), her answer probably losely translates to, "Well, I like that guy that you heard that I like, but I'll go out with whoever asks me first (including you)."
