Sibling Rivalry...PLEASE help

Hi my name is Kaylyn and I have a younger sister that I live with who just turned 11 and I CAN'T STAND her. Okay here's the story: shes always getting into my stuff. if shes not getting into my cds or on the phone while im on it then shes getting into my diray or playing with my superglue. One day she superglued my eyeliner to my dresser. Another day she superglued my nail polish to my night stand. And i just found out today that she superglued the lock on my diary closed. I b*tched at her for it right in front of my parents and told her that its on and she IS getting pay back!!!
I have asked my parents several times to get a lock for my bedroom door so that shell stay out of it but they said that i had to buy it myself. And my mom told me that if i do anything to my sister then I get grounded for 30 days and my cell gets taken away. But my sister has gone through my stuff so many times already and my parents find out about it each time and all she has to do *their way of punishing her* is she has to by me a new lock and diary...THATS IT!!! what can i do? my parents treat my sister like and angel!!! please help

The reason shes all up in your face and your stuff is because she admires you and wants to be like you, im glad my big sister was tolerant of me when I behaved like the younger sister you can't stand - trust me your the older sibling here so act your age and grow up hunny, life is too short enjoy your sister while you can you never know when you can be taken from each other...

as teh older sisetr you should set the example of how to act.you only 14 yrlsef your not that much older dotn waste all your time hating her. have soem fun maybe sit down and talk with her mayeb even pull some stuff on her liek she does to you so she sees how its like. as a older sister i used to get enraged with my lil ttle brotehr always in my space. now hes gone due to suicide at age 13 and iwish i had those times back to yell at him and to tell him what a brat he is. life is incredibly short soemtimes you never know what tomm will bring.make sure you tell your siter eveyrday that you love her cause tomm you may not get the chnace to do so.
