Dear Prongs,
Hey mate. How 'ya doing in heaven? If you got in that is. Oh, come on, you know I'm only kidding. You're the best friend I've ever had, Moony was a good friend too, but he's just not quite the same. Notice I didn't include Worm tail. If you only knew what he did you wouldn't either.
You probably think I'm stupid for writing this, I never was the sentimental type, but when Moony suggested it I thought it sounded pretty good. Maybe it'll help a bit, with the pain and all. Being back in my childhood home doesn't help much either. I know I said I'd never come back but no one lived here and after I got out of Azkaban, so this was a where I went. Yes James I said Azkaban. No jokes please. Do you know how terrible it is to be sitting just a few cells down from your death eater cousin? How horrible it is for people to think "Sirius Black, the murderer. I always knew he wasn't quite right. Apple doesn't fall far from the tree I guess." It hurts. It hurts a lot, But I didn't do it, and I know if you where alive you would have spoken up for me.
I've got to go, Harry just got here. Yes Potter, I said Harry. You're Harry. He looks just like you, and he has Lily's eyes. He's a great kid, you and lily would be proud. Oh speaking of Evans, say hello to her for me.
Your friend,
Padfoot
