Dear Annie: Our 14-year-old daughter is not a terrible kid — probably just a typical teenage girl. She can be rude and obnoxious, she talks back and curses, and she leaves her room an upside-down mess and is obsessed with her iPhone, constantly posting pictures of herself online and chatting with friends.
We have another daughter five years younger. We were concerned she might model her behavior after her older sister, and so we set rules about cursing and using her cellphone. Our 14-year-old could not abide by the new rules, and after much fighting, she decided to move in with her grandparents, who are much more lenient.
