Sibling Rivalry

I never thought I'd admit this out loud, much less to myself, but it's gotten to the point where I can easily say I'm starting to hate my sister. I really am. It's not like we fights twenty four hours a day or something, but maybe I'd rather have it like that. Every family fights. But my sister and I, now, we just don't talk. Not at all. And if we do, we're either asking to borrow clothes or she's telling me to "shut up cos it's none of your damn business anyway." To be blunt, my sister is a bitch. I know I can be a bitch too, but at least when I am it's more of a "I'm going to tell you how it is because you need to hear it, not because you want to" sort of way. My sister is an ignorant bitch. She brings her cell phone EVERYWHERE, which I guess is understandable, and it's not the fact that she brings it everywhere. It's the fact that she's always texting, even when she's over someone else's house or people are over ours. When we had a family party for my grandfather's birthday, my sister locked herself downstairs for half the time, and when she came up, all she did was text. I went out later, and on the way home, I had to pick my sister up from my aunt's house. I thought that was nice, since my aunt is always pushing for us to do stuff with her. She hasn't fully realized that we're no longer five years old, and it sort of breaks my heart, but I can't accomodate my friends and my aunt at the same time. So I was actually proud of my sister that she hung out with my aunt. But then, when I went to pick her up, she was lying the couch, texting, as my aunt chattered away, completely oblivious to the fact that my sister wasn't listening. It took so much will power not to yell at her, or smack her, or both. Honestly, that's fucking rude. I don't care if the person you're talking to doesn't care, or doesn't notice, it's still fucking rude. Not only that, but my sister manipulates everyone. Unlike I ever was, she's loud and outgoing in school, naturally causing people to flock and follow her. She convinces people to do whatever she tells them to, and really that's none of my business, but when you start transferring that to home life, now it's my business. All she does is sit her ass on the couch and text or watch television, yet she's asking for someone to get her cereal or make her a sandwich. What's worse is, my mom accomodates her. Not because my mom feels like she should or wants to, but because Christie won't take no for an answer. She'll ask repeatedly until my mom caves in. One time, I came home and my mom told me to make Christie a sandwhich. I look over, and my sister is sitting on the couch, with the television, the laptop next to her, and her cell phone in one hand. Excuse me? Oh yeah, I'm sure my sister the fucking eleven year old seventh grader, I'm sure she had a horribly stressful day at school. Oh yes, I understand she can't get her ass up to make a sandwhich herself.
HA.
Are you kidding me. I told Christie straight up, get the fuck off the couch and do it yourself. You know how. You just don't want to. Just because you can manipulate your stupid friends, it doesn't mean you can manipulate family. I won't let it happen. I am not your bitch.
It felt so great to say all that to her, you don't even know, and I can't even describe it. Unfortunately, my mom yelled at me and then forced me to make the sandwich.
But I did wait a solid thirty minutes before doing it, just to piss my sister off.
Now, her boyfriend (whose name is Douchepacker, for the record) is over all the time, which wouldn't bother me if he wasn't such an asshole. Really, I want to fucking smack the shit out of this kid. He seemed polite when he first came over and introduced himself to my parents, but as soon as my mom left the room, he nudged his (Douchepacker II) friend, gestured toward my mom's turned back, and whispered something, smirking. I almost blew a fuse. I swear to God. And of course, when him and my sister are downstairs, the door has to be shut. (CAN YOU PLEASE KEEP IN MIND THAT MY SISTER JUST TURNED TWELVE?!) Then last night, my neighbors came over (one of which was dragged unwillingly because Christie is manipulative, as I said, and made him come to make it seem more casual than just her and her boyfriend). One of them is a year older than me, a junior in high school, and she went downstairs for a second to ask her younger brother something and to say hello to my sister. My sister glared at her and didn't say hello back. Fucking bitch. So then this girl says, "Okay, I'll leave you guys alone now" and Douchepacker sneers and mumbles, "Finally. That would be appreciated."
I don't think you know how badly I wanted to knock his teeth out.
Earlier, before the rest of the neighbors had arrived, it was just Zac (unwillingly dragged neighbor), Christie, and Douchepackers I and II. I was in the room next to theirs because I had to shower and when I finished, got dressed, and opened the door, Douchepacker II coughed and said something that definitely had the words "ball" and "sex" in it. Douchepacker I started laughing and I turned to them and said, "Grow the fuck up." I bet my sister hated me for that, but my mom came down just then, and when she saw how pissed off I looked, she asked what happened. I said, "Nothing, just admiring how frigging mature kids are these days."
Now my mom wants my sister and I to magically get along, miraculously start talking again because when it comes to family parties, I'm the only one she can talk to, and vice versa. Although I have permission to read the whole time, Christie isn't allowed to bring her cell phone after being so rude, and now we're supposed to talk. In the spirit of Christmas, and just the desire the avoid conflict, I can easily be nice to her, slap on a fake smile.
But we'll never get along like we used to.
