Tell the little brat that except in California, a 15 year old cannot be emancipated; that in ANY state, including Missouri, she has to be able to completely support herself BY HERSELF (no moving in with a friend, no moving in with her friend's parents, no moving in with ANYONE - she has to pay rent, food, transportation, insurance, medical care, school expenses (oh yes, she still has to go to school), movies, CDs, clothing, shoes, shampoo, ALL BY HERSELF), and she has to have her parents WRITTEN permission to be emancipated.
