Time to kick butt!
You should fill a tub with hot water and dip her head into it and keep it there until she starts squealing and gasping for air and promising never to do it again.
hmm, but youre not desi are you?
Okay, I was kidding anyway
(so tired of studying)
I think since shes living in your home and you're obviously trying to meet her and your other sisters needs, you have the right to set the law according to what you think is un/acceptable behaviour.
Just be honest with her, tell her you're trying your best to accommodate the both of them and its not easy with your schooling. Bring up the whole 'we're in this together, and we're going to make it' crap, since its obvious your step mother doesnt care much and your dad is too busy to care (and the lack of attention is probably the reason for her rebellious behaviour anyway)
Make a mental list of what you think is unacceptable, and along with that give her an explanation as to why you think so. Keep that list very, very short, limit it to what you think are the most important issues to address with her (or else shes going to get real bored real fast, roll her eyes and tell you about how much you suck). Negotiate and set a curfew. Take the time and take her out to a movie or something, generally if you involve the rebellious punks in stuff, they start to mellow a little (especially the attention thirsty ones
) Make a point to speak to your dad about her allowance, if she feels like she can get whatever she wants and whenever, thats going to reflect in her general behaviour.
Make it clear that if she cant settle down and abide by your rules, you're going to ship her of to the aunts (actually, you may just want to hint at that or she's going to get defensive, i think). And if it comes to that, it may just do her good.
But whatever you do, dont make her feel guilty and crappy about herself, its only going to cause a major confrontation full of "I hate yous" and "you suck!".
Also, if she's telling you that you 'suck', it most likely is just a phase, be patient
oh, and Saya is a beautiful name
EDIT: I may just be really, really wrong. I've never had to deal with a rebellious teen myself, so i have no idea.
