at what age can a young adult leave home legally, and what can happen if they leave illegally?
My response:
The Federal law of "adulthood" specifies age 18. Unless earlier emanicipated, a minor can be hauled to jail for truancy. I'm sure there are other laws being broken, like curfew, but at this late hour, I can't think to list them all. Just believe me, there are many others.
Want to spin the Big Wheel of Fortune and try it ? If you do, you'll get the whole list from the police, the courts, and your parents.
