I've recently moved North, and I have a friend who lives where I moved from. She's told me several times her parents are crazy. I believe her - I've met them. They are hypocritical, judgy, controlling, and other out-of-their-mind crazy and stifling.
It concerns me, though, because she is nearly twenty and would like to visit me, would like to get a job, would like to go do things that aren't nit-picked by her over-possessive mom and dad. They ignore her and let her do whatever as long as she doesn't leave.
And then, when she's pretty much desperate for anything, they throw her the barest bit of attention. She's not very strong-willed (courtesy of her D*****-bag parents) and won't do anything, but it makes me angry and upset. My mom knows them, too, and her parents were like that.
More concerned with themselves with her. She had a very difficult life because of it. We want to help, but don't want to offend her. That they don't care what she does or how she is unless it inconveniences them is infuriating. What can I do?
