Intro
It's 6:00 PM. Guest stayed late to finish a class assignment. In the empty high school hallway after school. While walking past the sophomore classrooms on the way home, a noise is heard. It seems someone is still there.
He is looking behind shelves and other spots with a flashlight.
No way it's in a place like this... where did it fly off to? Crap.
Despite the words, the boy's expression didn't seem to change much.
I have to get home soon. Sigh. What a pain.
He continues searching for his pick.
