I didn't actually leave the comforts of home until I was almost 21. When I could actually leave home I never looked back. I was an adult, making money and departed at an appropriate time frame for me. Even at that age, it was a scary, sometimes unforgiving experience.
Today, on social media I have seen no less than three young people who have for whatever reason left home. Obviously, we don't know the whole stories of these people but it has definitely worried their parents.
One time when my kids were little we were in a chain department store shopping with a friend. I had always instructed the kids to keep a hand on the cart while we were walking so that I knew where they were. Well they decided to leave as I was getting something off a shelf. When I turned around they were gone. Of course I freaked out but my friend had them within eye view. "Hang back so they can't see you" she said. When they realized we were not around they raced back and never attempted to sneak away again. Several times the incident has come up in conversation as unforgettable moments.
You might at the time think you are hurting your parents or whoever is a part of the reason you are running or walking away from something. Today, no matter where you live be it large city or small towns--it is a scary, unpredictable world out there where sometimes a quick decision you make can effect the rest of your life. Social media can be a pro or con in making a bad situation worse or jumping to conclusion but my hope is that a bad situation can turn into a life lesson learned for these young people.
