Dear Uncle Sirius,
You didn't tell me Uncle Remus was going to be the new Defense Against The Dark Arts professor. I'm surprised, knowing how bad you are at keeping secrets. Luckily I'm better because I have to keep from my two best friends that my uncle and their new teacher has a furry little problem. Hermione will figure it out anyway so it'll be fun trying to keep her off his scent. I'm so excited Uncle's going to be our teacher. But I have to pretend to be disappointed because none of the other kids like their parents. I don't expect any special treatment but I was thinking maybe Remus could help me when I don't understand things for homework. I usually ask Hermione but she always says things like Oh that's so easy and then I feel bad. Anyway, Oliver says to tell you hi. This is his last year and I'm afraid he's going to break up with me when he graduates. I don't want to talk to Uncle Remus because, even though no one else would notice, I know Remus would start treating him differently. I didn't want to tell you at first that it was a guy because I know how overprotective you get. He's older, and bigger and I know you. Anyway, I think I might just talk to Oliver about it…just not yet. You've met him already, remember? Love you.
-Harry
P.S. I forgot my invisibility cloak, could you send Hedwig back with it?
