Maybe you should trust her moral values & not try to change them. You know some people are strong enough to handle themselves & keep their moral values even when they are surrounded by those who don't. If the values she has are truly hers, then I doubt that you have much to worry about.

I know I went to college years & years ago & it was completely different with the moral values then, but some people just value those morals more than any peer pressure can effect.

I don't think that someone should be pushed to loose those values or even loosen them up when they really believe how they are living is right.

Maybe by having a cop for a dad, she knows all the bad things that can come from straying from those values & has no reason to lower her standards.

Chill a little....just because everyone else does something doesn't mean that everyone has to & some people hold onto that belief.

It sounds to me like you are the one that's a nervous wreck about her. I am sure she will be just fine & find her college experience to be focused on what college is supposed to be about an education that gets you into a good career that you are satisfied with at graduation.

Hoping that you don't have as much to worry about with your niece as you are anticipating.
