And if you're serious about what you say, you should probably stop thinking of yourself as a "girl," too.
It's not intended as a slam -- it's just a fact. "Girls" are their parents' responsibility. "Women" are responsible for themselves.
For what it's worth, I think much of the difficulty in the US and elsewhere is that a lot of folks even in their 60s still think of themselves as "guys" or "girls," rather than as responsible adults.
Like kids, a lot of Americans are certain that somebody else -- the "adults" -- will clean up their messes after them. Unfortunately, there aren't all that many adults anymore, either in positions of leadership, or among the voters who put them in office.
Keep the faith, young lady as there are plenty of good people out there. You probably aren’t going to run into a majority of them on college campi’, but that doesn’t mean there aren’t some good ones there.
Don't get hung up over terms. This is both generational and regional. I know many 30/40+ women who want to be referred to as 'girls' both for fun and because it is a recapture of youth. Most of that little click of 'girls' are executives of some sort in their respective companies. If she is responsible enough has nothing to do to if she chooses to refer to herself as a 'girl' or 'woman'. It is obvious that she has her head on right, and frankly, seems better equipped for the world than most who refer to themselves as 'women'.
