Ok so, to answer this question, I recommend you read my last question about my sister. She acts like if something goes wrong, it isn't her fault, but someone else's. It's never her fault, when she obviously screwed up. She will blame me, because idk she thinks that she screwed up because of me, but in honestly, it was all her work. I call her a selfish queen, because she acts like a queen. She thinks everyone should say nice things to her, like your the best, your pretty for nothing, because she thinks that's what parents are supposed to do. But I think, you have to work and behave well and act well to even deserve to hear those words from your parents. She thinks she can get everything, while doing nothing, not even making an effort...she thinks she's the most beautiful girl and she always bosses me around, but I don't really want to fight with her so I just do what she says or follow her. I think sisters always have to listen to each other and do what one another says, but in my situation if she asks me to do something , then I will do it, because she is my sister, it's probably the right thing to do, but if I ask her to do something, then I'm always wrong, I have bad ideas, I am stupid, an idiot and etc., so she never listens to me and never does what I rarely ask her to do. When She asks me to do things, I offer my idea of how to do it, but we'll still end up doing her idea, then we screw up and realize that my idea, was in fact, better, but she will just deny it and say that it's all my fault, and that I should have not listened to her and did what I wanted to do , but how can I if she doesn't let me? I know it sounds confusing, but I really hope someone can relate and help me.

She is selfish, because if , for example, there are two apples, one is good the other is a bit bad, well, what I would do, is before choosing the apple I would ask people around me or my family members or who wants the apple which one do you want? I would say it's okay if I get the bit bad one, it's no biggy, but what she would do is quickly grab the good apple and not care who ever wanted that Apple....and it happens all the time, unfortunately. I want to find out do people like her change? Or are they born like that and still can't? She doesn't care if we lose a doubles match, but she will cry and blame me for her mistakes , which I clearly had nothing to do with. We lost a match And our trainer said that it was her fault, that she shouldn't have done so much mistakes, and then we he is done showing her her mistakes, she told me that it'MY fault that she did so many mistakes. And I'm always speechless and like wtf? Because I never blame her for my mistakes. I take responsibility for my actions. I can adMit to what I have done. All she does is denies everything I tell her about her , and she blames everyone except herself for her mistakes. There is always someone she can blame. If I screw up, I tell myself, dang it, I should have done that not this and then I eventually will get it right. But if she makes a mistake, she will blame either me or our trainer(like seriously? Blaming the trainer for doing what? Trying to help you?). So she will just keep doing the same mistake and not caring about what I feel or the trainer feels. I know this is really long and confusing, but idk what to really say than just blurt it all out into one huge textbook, anyone , please help me?
