This thread is bringing back memories...
When I was 18 my Mom let my best friend live with us for several months. We had a walk out basement. Almost every morning I would "keep watch" as my friends boyfriend snuck out the back, walked around front, rang the bell, and came in. He'd have breakfast with us before we all caught the school bus. I never even did that with my boyfriend, it never occured to me! My friend was scandalous.
If anyone ever asked my Mom, she would say I was her "good" child. Never a bit of trouble. I did a few wild things in my late teens, I was just good at not getting caught..lol.
My 19yo son and I were talking the other day. He said, Mom, someday I'll tell you some stories you won't believe... I said honey, don't bother, I've got my own. There are some things parents and children just don't share.
Serena, hang in there with dd. I'm waiting for mine to start rebelling but I think she's a late bloomer!

Hopefully she won't bloom until she's in college......
