I have this five year old sister who is REALLY anoying. She is forever anoying me. She get treated like a princess by my parents, she never gets punished for anything and she gets whatever she wants. My parents don't believe that she has the ability to lie even though she has lied to them before. Aparently she is just "playing"
Every time I ask her to do something she just says in her snobbist voice: "I don't have to do it" or "I don't wanna do it" She never listens to anything I tell her to do. She is forever coming into my room and when I tell her to get out she just says: "No"
She thinks that its all right to kick me and hit me if she is trying to do something.
How do I get her to start behaving?
