You pride yourself in being a hip parent who knows all of the warning signs. But with ever-changing technology, it's sometimes hard to stay on top of the latest and greatest trends, especially since you're not a teenager anymore. And to say things have changed since then would be an understatement. In fact, teens these days speak their own language via text - and if you're not down with the lingo, you may be missing out on some telltale signs that your teen is in trouble. Just knowing LOL and TTYL isn't going to cut it anymore. You need to get educated.
