Don't Own.
Here's the next part of Voldemort's letter to Lily, it will have spoilers (in fact, this whole story will probably have spoilers, so read at own risk):
Dear Lily,
I swear to merlin, woman! Your son is pissing me off. Not only does he and that oaf, Hagrid, foil my attempts at getting the Philosopher's Stone from Gringotts, but he doesn't even know he's done it! How dare he be so cheerful at ruining my plans yet again, mark my words he will pay for it... I will find a way to get past the protection you have given him!
Must you mock me, even in death, at the worst thing to happen to me since I let Peter Pettigrew become a deatheater?
Let's get this clear now then: I hate you. No, No, that's not even true either. Hate is too strong of an emotion to waste on a filthy mudblood and her son, who was only saved by a mere accident that I will not let happen again!
He won this battle, and only this battle!
Lord Voldemort
