they're under age.
Under what age?
Before, as always, you say something stupid again, let me remind you of two things:
1. We allow 16-year-olds to operate 2-ton machines at 70 miles an hour.
2. We often try 17-year-olds as adults and sentence them to 25 to life.
...because we decided that they have enough ability to tell right from wrong.
A 17-year-old girl, unless she is mentally ill, knows very well if and when she is abused sexually or is simply a prostitute.
It's amazing how a grand or two turns "abuse" into a party...
Hey, professor, "under age" is one word: underage.
