The beginning of the terrifying twist

I walk into my room finding it trashed, I only suspect my one sister Bethany doing it.
"Bethany! I told you to get out of my stuff!"

I scream to frighten her, I run to her room holding my diary but with missing pages out of it.
I look at her with frighten in my eyes.

"Oh come on Alison! All I want is to be friends with You and the rest!"

She says with sadness in her voice.
I shake my head and look at her,

"They are my friends not yours! Find your own, And the next time you wreck my room or even touch my stuff, You'll live to regret it"

I smirk then walk away. I clean my room. When I see my parents go to sleep I shut my door, I lock it so Bethany doesn't spy on me like a prev. I look out my window finding Bethany sneaking out in a black hoodie, I get confused and walk to my dresser, There I find a note. I gulp and back away from my dresser, I sit on my bed and began to think.
