I have a younger sister that's been disagreeing with me a lot lately. We just had a huge argument which is why i decided to sign up here. She said sorry, but her appologies mean zilch since I'm almost positive she'll go and do it again without regard to my feelings.
She fights with my mom constantly over the littlest things and I'm forced to listen to it. When you talk(or argue) with her it will go one of two ways. Sometimes it'll sound like she's being sincere and that she's listening to what you have to say, but other times she'll just repeat the words "I don't care, I don't care" and act like she has no idea where you're coming from.
I know her behavior seems normal and it's just how teenagers "are", but it's been getting out of hand. Not to mention she began using hurtful, ugly words toward me and even my mom long before eigth grade. It might be her group of friends, or maybe she's hurting on the inside, I don't know.

My parents have tried grounding her, and taking away priveledges like the computer and tv because of the way she acts. They even took the door off of her bedroom because she snuck out through the sliding glass door in her room. You could say that's pretty much everything besides, well, therapy.

I was never like that when I was 13. Any suggestions or similar situations?

my sister is like that, i find that when they get in the argueing mood and you cant talk to them just walk away and ignore them, because she will want a reaction out of you and she wll want you to figt back, if you dont she will give up eventually, even though it may take a lot of tie and a lot of patience. thats why i cant do it cause i get annoyed too easily.

When I was 13 I din't even care about things that much at all.. I was too much into video games, did not think of what I look like at all, did not think of girls... pretty much chill.

Well you know, times change. Teenages nowadays are too "crazy". Things in the media/others influence kids and tell them that being rebellious is cool. Sometimes if gets too much.

But in my opinion, your sis is just a total bitch. Maybe she thinks she can always get away with the stuff she does. Even if you ground her she sneaks out... so that means she does not really care about the rules you and your mom established.

I don't really know what to do to people like that besides the things you already said. Sometimes these kids just realize that theyre making everyones life a living hell and they would just stop.

My sister is 13 but she doesnt fight with me or my parent.

I, however was a diffrent story, when I was that age my family had moved to a new town so i was in a new school with no friends. I was very insecure and fought with my mum almost every day instead of the people in school who was not very nice to me all the time.

Maybe the reason she's fighting you and you family is that she is under alot of pressure in school or with her friends and takes out her anger with you instead =/
