First of all I have no idea what the details are for this girl.  These incidents are becoming a dime a dozen for teenage girls since I've seen posts about 7 other local teenage girls missing this week, and countless others from other states which make me wonder.   Usually seems to happen not too long after a Facebook meme saying "Sometimes you just have to disappear to see who will come looking for you.  Those will be your only true friends."   Seems to be a new version of the ice bucket challenge.    I can hear my mother's haunting words right now, "If your friend jumped off a cliff would you do it too?"
