Is it a right of passage of teenagers to think it's okay to speak rudely or roll your eyes at your mom? I try not to allow disrespectful behavior but it still happens. I used to be a saint and considered knowledgeable in my home. Now, I'm not so smart and a pain. And so many other moms of kids my kids age are saying the same thing. Is this a stage? What does it mean when very polite and loving kids turn into know it all teenagers?
