Dear Moony,
If you found this it's probably too late. Don't worry about me I'll probably be at James'. I want you to take care of Harry and I know you will, not because I said so, because you are a wonderful man.
But this letter isn't about Harry. It's about me, about you, about us, if I dare say so. Its about something to shout from the mountaintops and from the shores for the whole world to hear. Hear that I, Sirius Orion Black, am in love with you Remus Lupin. And I hope you are too, but even if you're not, that's fine because I'll be watching and protecting you. I'll be watching as you eat your breakfast, as you go to sleep, as you get married, as you grow old and when the time comes, I'll be there for you, to welcome you back and make sure you're not scared, although I doubt you'll be. The one thing I can't guarantee for is your smile. So I want you to promise me that you'll smile every day. Tonight go to bed smiling and make sure everyone else does too. I'll miss you.
Love
Padfoot
