Harry,
I want to start by apologizing to you about the way I handled myself tonight. I wasn't very mature and I feel bad about it. I brought Jalil into my home because after your parents died and Sirius was taken away, someone took me in, even after they found out about my condition. Someone took care of me and I wanted to help him because he needed it and everyone deserves a chance, even monsters and ex-Death Eaters.
I've never actually been disappointed in you before, even when you kept running away. Until tonight. You chastised me for helping someone. Severus Snape murdered Albus Dumbledore. He told Voldemort where he could find your parents, so he could murder them and you. He's killed plenty of people. He's tortured more. He's hated you for half his life because you're your father's son, he's hated me for most of his life because I'm sick. But you gave him a chance, you gave Severus a chance.
I took someone in out of the cold and gave them a chance.
You're mad at me and you're having sex with him.
Your mother and father would be just as disappointed as I am, that you're so unwilling to help someone in need. But neither of them will ever know, they shouldn't have to have their image of you tainted like that. You can tell it wasn't me who raised you, because I would have done it right.
I love you. Unconditionally. If you ever forgive me for being a good person, drop me a note. Let me know. But until you do, I hope you stay well and happy.
Remus
