So they were learning something that was related to weather; and with what they had been asked to bring with them to class today, did that mean they might get rained on?

Silvia had pulled up a nearby chair and sat down, pulling out her notes and textbook. She listened as her fellow students explained the protego charm, which she was not unfamiliar with, having learned it in DADA a while back. And this variation of it sounded very useful.

Questions? None that she could think of at the moment. So she settled for writing the spell down in her notes, as well as any other important bits of information that came up during their question-answer session. Sounded like it would be an interesting lesson.
