Has some of the craziest parents ever. They made her go into a private school where each day is from 8AM to 6PM, and are super-paranoid (a few results of which have been that she's never trick or treated or been on a train, and yes those are rather random examples). They don't want her hanging out with me because I'm not Jewish, and they seem to ignore (or simply not recognize) the fact that their iron fist in raising her has conditioned her to avoid her parents as much as possible, which creates an air of distrust between parent and child. To this effect she has gone as far as listening to her iPod during one of her mother's long-winded lectures. Ergo, she's entirely unable to console with her parents on anything. Sadly, my friend doesn't even recognize that this is an uncommon occurrence.
I'm starting to worry that this could have some serious negative effects in long-term, or that she may be so sheltered she gets herself into a dangerous situation when she finally explores the real world. While it generally wouldn't be my place to do anything, I really am getting worried about her and I really feel like I should do something to help. The problem is, I have no idea what I can do.
I've suggested my friend openly express her distaste of her parents (and particularly her upbringing), but she says she's already tried multiple times, and her parents seem to be the type prone to denial.
What do I do?
