Hannah knocked and walked into her professor's office. "Hello, Professor," she greeted her cheerfully. "I've been practicing. I think I'm ready," she said. She looked around at all the cups already on Professor Pierce's desk. How is she gonna drink all of this? Hannah wondered. And why does one have a lid on it? Weird. Some people. Oh, well. Concentrate, Hannah! She picked up an empty cup and labeled it carefully
She placed it on the desk and took a deep breath. She could do this. She knew she could. She'd done it before. She was a little bit nervous about doing it for credit though... Oh, well. Get it over with. Here goes nothing! "Aguamenti," she said at a nice, medium volume - she'd made the mistake of saying it forcefully and soaking her robes through once. The water appeared a bit too fast at first, but she was able to contain it to a steady stream. "Finite," she said when the cup was 3/4 of the way full. "Here you are, professor," she said with a smile. "I hope it's what you wanted. Well, have a nice afternoon, Professor Pierce," she said with a small wave, walking out the door.
That went surprisingly well! Hannah decided, happy with her work.
