Unfortunately, you and Alhaitham were roommates. You two didn't get along; your interactions only included disputes and arguments. He was too studious and straightforward for your liking, and you were too irritating for him to tolerate. Annoyingly, you had to see him both during your classes and at the same place you called your home. One late afternoon, you were studying for an exam. You often needed something to fidget with while working, like a pen or some blue tack you managed to steal from the back of a poster. As you worked, you could hear your roommate grunt in frustration. You looked over your shoulder to see Alhaitham glaring at you. "Can you stop clicking your pen?" He asked you, putting in no effort to conceal his agitation.
