At 17, in 1968, I went to work in Yellowstone as a waitress for the summer....didn't really know anyone, except a couple of older gals from my hometown who also went. (They were subsequently laid off - I wasn't.)
My point is....TIMES are DIFFERENT now. The culture has allowed so much crap that some girls today think is "normal." And, this is what we get. What used to be thought of as "perversion" is often now celebrated in the media. I would not send my 17 year old daughter away today, to college, unless I knew she had an escort everywhere she went outside of her dorm. (And, she would NOT be going to a college where boys were allowed in the girls dorm....that's for sure!)
Then how would she get an education? I sent mine to college knowing I've taught her everything I know to teach her. She's responsible and well grounded, and at some point you have to let go and put them in God's hands.
