Extend the Story - Add a Room

I know It's really early, but I can't sleep. Yesterday at school I asked permission to go to the bathroom, and the teacher granted my request. I left the room, but instead of going to the nearest bathroom I went to the one towards the west wing. What's wrong with killing time. After a couple minutes I found myself near the west wing gym. I looked for the bathroom, I had never really been there before, this is were the older kids stay. The hallways were well lit, and the paint was not chipping everywhere like the paint in our hallways. The floor was clean and neat. I could tell the cleaning lady had gone past not to long ago. While I was looking for the bathroom I listened in the classroom. The teachers were smiling, and the kids all rose their hands to answer questions. "This is so different from what I am used to see..." I looked out the window. I saw the green playing fields, the park, and the benches. I saw younger kids hanging out near the garden. This side of the school definetly seemed like the perfect school, but near the east wing things are ten times worst. The fields were brown and yellow. The teachers hated their job, we would just talk all class and they wouldn't care at all. This magic place will be all mine next year, I thought.
I walked past a sign pointing left, I recognized the word restroom, so I decided to go that way. I finally found the bathroom. The second I stepped in the girls started screaming and yelling.
"What are you doing here?" this tall blond girl said to me.
"I was just looking for a bathroom, excuse me." I said, as I turn around and enter a stall before she could say anything back.
I heard girls moving around, whispering to one another. I got out to find the same blond girl waiting for me near the sinks.
"Answer my question, what are you doing here? This is the girls bathroom you knucklehead."
"Yeah I know this is the girls bathroom, which is why I am here. Although why is it only girls in here? But I don't care, I have to go now, see ya'll later."
I left the bathroom, and went back to geometry. Later that day I heard rumors that a boy named Andrew went into the girls bathroom. I thought about this all night, and I still can't figure out why that is so bad. I know I went into the girls bathroom, since when is that not a thing?
Anyway let's go back to killing Allyson. I like the knife idea, but I will have to be very careful. The teachers can't see me with a knife in school, they will definitely send me home for the day. I have a knife in my room but you can't tell anyone about it. I am hiding it under my clothes, in one of my socks. No one knows about it. Although I have let Allyson borrow it only once. I know she has a pistol in her bag. I guess I can hide it in my backpack, like she does. I can get out of bag checking that morning. Avalon, likes me too much. This sounds perfect, tomorrow is the big day. I have exactly thirty hours before we go to the gym. Meaning I should get everything ready. And by that I mean put the knife in my backpack. Let's go over everything.
First I put the knife in my bag. Second I wait. Third I have to sneak up behind her. And finally I can just stab her in the back. What do you think?
Give me a second.
"Andrew time to go to school get your stuff and hurry it up!!" my mom shouted.
"Yes mom, I coming. Give me break."
"No, just get down here. I don't have all day Andrew. I seriously wish you would be more like Kamilah."
"I know mom, you say so twenty four seven" I yelled as I walked down the stairs.
If I haven't mentioned so yet, we have a cat named Kamilah. She is nice and all, it's just my mom is way to attached to her. Her whole life is about Kami this, and Kami that. It gets on my nerves. The day Kamilah will die, my mom will probably die with her. Well I got to go. See you tomorrow, for the big day. Just make sure to tell me if you think everything I planed out is good.

Maybe, I'm not really sure
