The beauty of having a 18-y/o in the house is not caring whether she's home for dinner every night.
She'll be going to college, working and dating, so I doubt we'll see her much. At 17 she's going to high school, working and dating, and seems to think it's an imposition on her civil rights to expect a little accountability to her parents.
Ah, yes... Kids tend to want to be independent before they really can be independent. It may be unpleasant for a while, but the time will fly by, and she will turn 18 rather quickly.
17 is a tough age for a girl.........I remember my girlfriend when she was 17................................................................................................................................................................................AUUUUUUUUUUUUUUUUUUUUUUUUUUUGGGGGGGGGGGGGGHHHHHHHHHHH!!!!
