Why must I go back?

Down the hallway I walk with my backpack at my side. People are pushing past me. I enter the classroom silently. Everyone else had arrived on time. Finding a seat was most easy and difficult. On the first day the seat you choose means everything. If the teacher asks you to remain where you are seated for the rest of the term, then that is where you stay. My fellow classmates talk gaily as I rest my head in my arms on the desk. They have no idea, but neither do I.

I small tap on my shoulder makes me look up through my sleeves. A girl is hunched over the length of a desk and is peering at me. She asks if I brought my calculator to class. I tell her it was on the syllabis, ofcourse I do. Then she asks if a scientific calculator would be fine. I tell her we were required a graphing one. She asks if that's what I have. I say yes. Then she whips out her brand new graphing calculator and asks if she can import any games I might happen to have. I tell her I only have one: Two Player Bomberman.
