Cal laughed lightly, a bit flattered that Harrison would mistake him for a real student. Although... he supposed that was not such a bad assumption, considering that he was the right age to be a student. "No, no... actually, I'm just on the janitorial staff. I audit all my classes, which is why my name isn't technically on the register. I'd love to take classes for real, but I'd never be able to afford it. I enjoy the classes though! At least that's something." Cal shifted a little. He didn't usually think about his financial situation, or that it would be nice for him to actually take real courses. But clearly that's what he did think, otherwise he wouldn't have said it. Ah well. Perhaps someday.
