I have two daughters. Trust me. This would not even be a question. NO! It is the parents responsibility to teach them right from wrong. Sleepovers with guys is WRONG! outside of marriage of course.
Both of our daughters are now married with daughters of their own. They have both said thank you for being the parents we are.
They could always blame me for being the mean mom and I wouldn't let them do things like that. They also knew they could call (and they did) any time of the day or night and we would be there to pick them up.
