As he pulled out the chair, Mario saw a strange little box
sitting on it. He recognized it as something he'd seen
on Mario's dresser and was annoyed that his
roommate's disarray was now creeping over to his side
of the room.
Without paying much attention to the box, he tossed it
over onto Mario's bed and began to do his homework.
An hour later, Mario entered and tossed his books
down.
