Mr. Nathan, the principal, is the only other person who saw the creation of this school, so both of you are neutral with each other. But you want to get close to him, instead of having a business-relationship only. And besides, he seems to bite anyone's head off in the school (students, teachers etc.) except yours.

"Have you cleaned the halls, already?" He asks as he comes from his office. As the janitor, of course you have! Right?
