Intro
Morning! Today I become a high school sophomore! There's a class shuffle, and the people will be different too! I can't wait.
I eat breakfast, get dressed, and open the front door! A new life begins.
I arrive at school. Guest checks the class list, heads to the classroom, and sits at the desk where the name tag is placed. It's the fourth row by the window. And who is the neighbor I'm curious about?
