Sibling Rivalry

Is it wrong to hate your sister? To really and truly despise her? My sister is visiting home for spring break, and she has been a terror for the last 3 days, so much so that I've quarantined myself in my room so that I don't have to put up with her crap. She's belligerent, abusive, combative, everything but actually violent it seems sometimes. I speak and she screams at me for no rational reason at all, unless it's hormonal in which case I'd cut her a little slack. Then today she expects me to drive her into the city to check out a neat bookstore, because she's recently decided that she likes to read (the only positive influence that Twilight has had on this planet in my opinion). I decide to be the bigger person and grudgingly agree to take her, but decide that I'm too tired to drive, so ask her to. She goes off because she doesn't have insurance, though our parents could give her permission and be covered, and says she's not comfortable driving there anyway. When I maintain that I'm too tired to drive, she declares that she is done with me, stomps out of the room, up the stairs, and slams her door. Now going in the first place was meant to be a favor to her, so at this point I've had it. If she wants to be a little bitch yet again, then I say fine, she can deal with the fallout and I'm done being the nice guy. After four days of censuring what I say, how I speak, what I can and can't do, I've had it up to here. The next time she comes up and informs me that I need to do something for her, I'll tell her that she can just go to hell.
