Dear Ron,
I know time moves differently where you are, and for all I know by the time you get this ten years will have gone by and you'll have forgotten all about me - or you'll remember me, but only very vaguely. Maybe you have the occasional random thought about that mad Muggle who used to try and make you run laps at sunrise, and can't quite remember my name.
Or maybe I'm being stupid, and you recall me very well, and have nightmares about falling once more into my clutches. Mwah-hah. Mine is an evil laugh.
Anyway. I hope you're doing alright, you and Hermione and Harry. I hope you're enjoying classes, flying every chance you get. I hope you've found an excuse to pop Draco 'Born With A Silver Spoon Wedged Up His Ass' Malfoy right in the kisser. I hope you're running, and practicing with your knives, and thinking not-too-terrible thoughts about me while you're doing it.
I hope you're all well, and whole, and happy.
I miss you. All three of you, but you especially - a teacher shouldn't have favorites, I know, but I do, and that's you. You've been a delight, Ron, a good friend and a wonderful student. I couldn't have asked for a better. Remember that, no matter what happens. Remember that I'm proud of you. Remember that you're my favorite redhead, and my favorite Gryffindor.
No matter what happens, Ron. Remember that your surrogate sister loves you.
