Maybe she was at home?
I know it's hard to believe, especially here on Free Republic where we all have perfect children, but sometimes teenage girls do crazy things like put on their jammies, say "goodnight mom and dad" and go to bed. And then later, much later, they wake up, put on something cute and sneak out of the house to do things they shouldn't be doing (but that their parents probably did when they were teenagers). And then a few hours later they sneak inside through a window so no one hears the door open, put their jammies back on, 'wake up' and say "good morning mom and dad!"
Crazy, I know.
Anyways. Sad story all around but a lesson to the rest of us (especially those parents who obviously don't post on Free Republic because they have teenage kids who do this kind of stuff): Know what you're shooting at before you pull the trigger and heartbreaking tragedies can be avoided.
I know people who have had that happen with a daughter, not even 14.
