Mark Twain is said to have advised that when a child turns 13, his parents should put him in a barrel, close the lid, and feed him through a hole in the side. Then, when he turns 16, plug up the hole. I offer this quote not to advocate incarceration or starvation as a healthy response to teen rebellion, but to help you see that you’re not alone. In fact, cross-cultural research shows that there are two universals when it comes to teens: spending less time with their parents (and more time with peers), and doing things differently from their parents (teen rebellion!).
