"You really should study, you know." I told Ron. "We have that huge test on History of Magic soon, and you and I both know that Proffeser Binns isn't going to go easy on us."
"What's the point?" he said. "I won't remember what I read, anyways."
"Look, Ron." I said."Do you want detention, or do you want to be able to go to Hogsmeade tomorrow?"
"When we go out into the real world," he snapped, "will it matter that the Bouncing Charm was invented by Mary Whats-her-face?"
"Her name is Martha Dewtap, and she just happened to be the wife of the second Minister of Magic."
"As long as I can cast it, it shouldn't matter!"
He pointed his wand at Crookshanks. "Monarchphilium incantio!"
"RON!" I shouted, "Take that curse off! You're making Crookshanks queasy!"
"I will," he said, "once you let me borrow your notes."
"RONALD!"
He looked at me as if I had just cast the spell on him.
"Alright," I said.
I went over to grab my notes. I put a Slippyfingers Jinx on them and tossed them over to Ron.
"Thanks, Hermonie!" he said. He pointed his wand at Crookshanks and cast the countercurse.
I waited as he attempted to grab the notes, but failed. After a few minutes, I pointed my wand at him. "Monarchphilium incantio!"
"Now, if you'll excuse me," I said as I walked over and removed the Slippyfingers Curse, "I'll be taking my notes now."
