Hello, I would like to get an idea what do people think about mixed sleepovers and generally sleeping over at houses of opposite sex teens. I have a 15 yr old DD who was invited on two occasions to stay over at a 15yr old boy's house. IMHO this is inappropriate at this age and I politely refused both times, but if it happens again, what do I do? I do not want to appear rude or to lie to the parents. Do I just tell the truth that I do not agree with this or what? She has never been to a mixed sleepover and will not be going to one. AIBU and overprotective? Please help!
