[Failed Privacy Hex to Kirley]
Did you happen to toss your underwear on my bed or something in your rush to get to class today? Because these definitely aren't mine, and I really hope they're not anyone else in our dorm's. Don't really want to be mistaken for Pepper, now.
You're my best mate but that's fuzzy bunnies nasty. And don't blame it on me, I woke you up in time, not my fault we were almost late for Herbology.
Oi, speaking of Herbology, you think on Friday we can get there early so we can not be in a group with Tonks and Proudfoot? Bit awkward still.

Added later: Guess you all can read this, then? So be it. I'm done hiding things.
