"I offer them yearly, and typically they're for those who are graduating. I have never approved someone before that point, as my internships tend to lead to full time positions, which you'd be incapable of as a student." Persistent was good, yes, and the boy before him wasn't unintelligent. He just was not prepared yet for what the job would entail. "I commend you for your work.

"There are a number of jobs that will be open to you while you attend school, but the internship begins the day after schooling ends for the year, which means that I still will not have your OWL scores in hand. You have achieved good scores in my class so far, but it is only September and that means there is a lot of work ahead as well."
