Harry was surprised when an unfamiliar owl swooped down in front of him and dropped off a letter, he wasn't sure who it's from, but when he saw that it was written on normal paper instead of parchment, he knew it's from Mayumi.
"What does it say?" Ron asked.
Harry frowned.
"Well, she said that I need to be less dumb and read more about mirror riddles." He said, looking through the short, brief letter quickly, "she also said that you really should stop letting scrabbers on your bed." He paused, "PS, please do check the chocolate frogs."
