Ok, I remember being kind of like that when I was that age, and my oldest daughter is like that now. A relative of mine who has already raised her children, said that when they start to go through puberty, they start to have trouble controlling their feelings and attitude. With my daughter, we just try not to lose our temper if possible, and stay consistent with the rules no matter what kind of attitude she gives us. Such as, bedtime is at 9:30p.m. no matter how much she huffs and puffs, and complains. It's still 9:30p.m., and she's going to bed no matter what. That's just one example, but it works. She might get mad, but she still does what she is supposed to do, because she knows that there will be consequences if she doesn't. She also knows that she can't use foul language or scream at us, or anything like that, because there will ALWAYS be a consequence....not just sometimes, but everytime until she gets the idea. I'm telling you all of this, because it has worked, and she is a very well mannered, and well behaved girl even though she might still roll her eyes or give out a long sigh every once in a while.
