Snap, Instagram and Tik Tok.  If you are the parent of tweens or teenagers, those are three words you probably hear fairly often in your house.  To today’s adolescents, social media is the main mode of communication.  Heck, Snapchat’s tagline is “Real Friends.” For many of them, it is even their main platform for social interaction. Gone are the days when a teen would curl up up on the couch and talk on the phone for hours on end, today most of them communicate in silence.
