Disappear

A story about a 13 year old boy.

I walked on 3 minutes late. Everyone starred.
I took a seat in the second row.
Time slowly ticked by.
The kids at the back cursed at the bus driver. He didn't hear.
I listened to the sound of the engine.
Something hit my shoulder and rolled onto the seat. It was a crumbled piece of paper.
I opened it. I read it. I wish I hadn't.
