A classroom full of students rustles their books into their backpacks. A few students in the back of the classroom pass notes, while two others play finger football with a folded up piece of paper. The noise in the room elevates as the students begin chatting amongst themselves. The teacher closes her book and begins to erase the blackboard clean. When she finishes erasing the blackboard, she removes her glasses and sets the eraser down on the ledge of the board. She thanks the class and reminds them that their homework is due in the morning.
