My vote is with Partice's advice. If it's crappy at home, and she's at least responsible enough to look for a job, then so be it. Not everyone is mature enough to do emancipation, and not all crappy home situations are just dramatic teenage story telling. look up programs like the one patrice suggested. And also, working at movie theaters ain't so bad. i did it for awhile. it's better than fast food. However, if she can find a good program, and stay in school, and make something decent of herself, its all a bigger Fuck You to the parents. Maybe check out something like
Job Corps, they put you up in dorms, while you attend vocational school, and you get an "allowance". i don't know how it works with minors, esp if you become emancipated. But the program is for ages 16-24.
