Is it normal my little sister is an immature bitch

I am fifteen and my little sister is thirteen. I don't know when she started acting this way, but for the past few years she's been acting really immaturely, at home and in public.

She's acting like a spoiled little brat, who always want unnecessary things and never thinking once about our parents' financial situation. She's also really rude towards my parents, and although she never uses cuss words, she behaves really loudly and obnoxiously when things don't get her way.

It's really painful to watch, because I want to love her, but it's really hard to. My parents try not to notice, but I know they feel really dissapointed when my sister behaves like this, but try not to show it. One time, she threw away her dinner just because she didn't want to eat it. I never behaved this way when I was thirteen, so why is she doing this??

I'm VERY sure that it's not her friends' fault. I am very close to each of her friends, and they are all very mature and sensible, so that's peer pressure out of the window.

Please help me? She tends to wake up really late, and would also throw tantrums (at the age of 13, I KNOW) during breakfast, and thus I'm always late for school...

    You must make her go naked at home, in public, and have lots of sex with her. Then she will calm down and act properly.

    I think counseling would be a good idea, assuming you can afford it... I'm very close to my sister, but she can act like this sometimes too, just talk with her one on one and tell her you love her, even if you feel like she's being a bitch.

    Don't expect everyone to act the same way you acted. She must be really hurt that she's turning her sadness to anger.
