My Dearest Lily,
As I set under the tree of where we first meet writing this letter for you, my heart aches with pain wishing I could go back in time and undo that terrible day. Hoping things would be different if I didn't call you that unspeakable name. We could have save our friendship but, I know you would still end up with James. I wouldn't have chosen power to cover up the pain in my heart. You would still have a brilliant son that has your eyes Harry Potter. Lily I wish you could see how much your son Harry has turned into a young man you would have made a wonderful mother.
Love always
Severus
As Severus walks to the Lily Potter grave he gently puts the letter down and walks away
