How to deal with my sister disrespecting me?

I agree…hide your things.

Sounds like she is really trying to get your attention for some reason…maybe sit down and talk to her - ask her what’s wrong and why she’s doing what she’s doing.

if you have a younger sister, just hide your things if you dont want to tell you parents. i know how you feel, or, just stand up to your sister and tell her the way you feel. if you have a fear though of your sister, then i would just hide the important things from her.

I think that you should put the responsiblility of her behavior on your parents.. it is their duty to deal with it. You should not have to. They are the grown ups, let them figure out what to do. They could send her to some kind of place that deals with kids like this… she is way out of line…

If you can talk to her, you might try to find out why she is acting like this.. prehaps she might have been raped or something, and no one knows and she is taking her anger out on everyone because she can’t deal with the rage inside, this is just a thought, might not be right at all, but, something is causing her to act like this, if you can find out what, it might relieve the situation.

She wants resistance and want to see limits! If you don’t give her resistance/show her your limits on smaller things, she’ll become more extreme! So my advice is, tell her clearly, that it is not ok what she’s doing and that she shall stop that!
