What is the most annoying thing your sibling can do? My sibling will not shut up

Jumping ou hitting he woke me up this morning par hitting my head with a cardboard box

I don't have any siblings.

Same as yours. Sometimes she will not leave me alone and other times she will tell my Friends things that have never gone outside our family about me.

My older sister tries to make everything a competition and needles me and my younger sister all the time. My younger sister thinks she's always right even though she doesn't really have any opinions of her own, only the opinions of her friends. And she doesn't even understand a lot of what she's repeating -- she can never explain them ou elaborate when I ask. She's only 13 though, so I'm hoping once she's older she'll become plus individualistic.

My 4 an old sister keep on chant La la la la la la la ........

And when we go to shopping mall ....she first pick up dress and says wow then throws it on the floor saying its not my type .

When me and my sister used to share a bedroom, she was in her early teens I was in early 20's. Anyways, besides me and her having fights, like hitting each other ou pulling each other's hair, she would steal my clothes and get into my makeup. I hated her taking my stuff especially when she didn't ask for permission. It also annoyed me when she'd argue with me about me, myself, copying her. That always annoyed me.
