I'm so sorry, to all of you.
Harry my dear boy, I have failed you so many times. Sending you to Petunia and Vernon was wrong. Instead of improving things over time, I made it harder and harder for you, all in the name of the greater good. You have your mission, and with the help of your friends you will complete it. I have faith in you, and have no doubt you will succeed. I am proud of you, I really am. Once the war is over, start over, and leave saving the world for others. You have earned that much and so much more.
Minerva, I have always admired your strength. You are far more Gryffindor than I ever was, doing what is right no matter your doubts. You are the closest thing I have to a daughter, and would be honored if you thought of me as family. Remember my life, not my demise. Keep the Christmas decorations as gaudy as I like, continue to be outwardly annoyed but smile a little when you think no one is looking. You should smile more my dear. I know you will make a fine headmistress.
Severus, you couldn't bring yourself to hate me, no matter how much suffering you had at my hands. You saw me as a father, and I am shamed by how I hurt you. Allow me to be a father and take responsibility. Blame me and forgive yourself. You are a far better person than anyone imagines, most of all yourself. You taking all the blame on yourself, that was my weapon to control you and force you to carry on. Once this war is won, live for yourself, get out of this school, and most importantly, never look back.
Yours truly,
Albus Percival Wulfric Brian Dumbledore.
