love=stab? Cool, a new metaphor for me^^

But to the opp, >>54 could be right. However, this is no reason not to be firm with her. I would generally not recomend slapping her, but if you at some point or another actually feel physically threatened, and if she wont accept time outs or television bans, it could at some point become the only option. I dont quite understand how the female mind works, so maybe this may have no effect on her general behavior, but on the other hand, it may scare her just a little bit, which is the first step to gaining respect.

Another thing you could do to try and gain her respect is ask for more priveleges from your parents to show her that you are her elder, that you are more mature, and that your level of power is closer to that of an adult than that of a child.

Also, just out of curiousity, how did she learn all of this stuff? Have you considered that maybe the way she acts is a direct result of the influence of you, your parents, and the television? Perhaps you could suggest to your parents less television watching, getting your video games in your room, and less arguing and swearing in front of her to help curb her behavior.

Finally, when you think about the way she acts when she gets criticized, does there seem to be a reason for this? For example, when she was younger, did she have some traumatic events related to criticism, or was she just harshly criticized in general? And when shes at school, does she react the same way? Because if she doesnt, thats evidence that she can change the way she acts any time she wants, and shes acting the way she does at home out of pure choice, which I would thing backs up 53s point a lot more.
