I must be a mean motor
scooter, cuz I never let my kids get away with that kind of stuff. Oh they tried to do it, believe me, but they knew when they went too far. My oldsest daughter was the worst. I'd come down on her and ask why are you behaving like this? She'd say I don't know, and then write me this huge apology letter later.
Kaitlyn is at the testing age right now too. When she starts in at it, I stop her imediately and ask her what is with the additude? "Do I deserve to be talked like this?" Usually this stops her in her tracks to think on it. I will then say, "I'm just trying to have a nice converstion with you, and you are treating me like I'm stupid or something. Do you think I'm stupid? Do you talk to your friends like this?" Or I will just tell her in my very
motherly 
tone to just nip it in the bud! She knows that is the time to shut the mouth!!

But this is something Dave and I have instilled since they were young. They have never been allowed to back talk. If they just muttered something, I would ask if they had something to say. Or it was "What did you just say?" Usually it was nothing of course.

My Mom and Dad did the same thing to me, and it scared me to death.
But all of this stuff that they go through is all for a purpose of course. They grow up, and this is their time to start spreading their wings. And I have to take all of this into consideration too. If they didn't do any of this, then I guess I would worry about them, and their maturing.
I tell you, it is a fine line being a parent. When to say no, and when to say yes, and when to give in.
OK so much for my mothering talk.
