Night was happy that her friend had saved her a seat. In some ways, Astronomy seemed like a Muggle subject, because she'd studied the stars back in Muggle school. However, even though she'd never learned this, or even thought to ask, Night expected that the wizard community had sent people to the moon, and probably even further, far before Muggles had.

What else did she have to learn about wizard astronomy? Now that she thought about it, Night realized there was so much she still needed to know about the wizard world, and wizard/Muggle relations.

She looked around for the professor and felt a small surge of apprehension when she saw he wasn't there. Was this going to be like the Defense lesson from a few weeks ago, but at midnight?

That in itself was something Night both loved and hated about astronomy. She was a night owl, of course, so the timing worked well for her. However, she would prefer to be reading or studying on her own during the time she wasn't sleeping.
