I have to say, I liked writing this letter the most. Harry's was awkward, Remus' was empty, and Sirius' was mushy, but Snape's letter... XDD

Potter,

This is stupid. I don't know why I'm even doing this.

Oh. Albus is staring at me from across the table. Well, that would explain that.

So what am I supposed to say to you? I never liked you; hell, I hated you. With a passion. And you didn't exactly act like my friend or anything.

I hope you're happy. Your son is a brute. He never gets his work done, he's always cheeking me, and he can't do potion work to save his life. He's an arrogant little twit, and it's high time somebody puts him in his place. I can only hope that person will be me.

You might as well tell him in your letter to stop strutting around the school like he owns it, much like you did. Just because he temporarily defeated the Dark Lord doesn't make him royalty. He and his ridiculous "friends" (more like groupies) are always pestering me and getting themselves into trouble, and guess who has to get them out? ME.

The only reason I helped your little monster four years ago was because I owed you. I didn't care about the brat in the least; in fact, I wonder why I even bothered. He's just given me grief, after all.

Do not think my hate is unfounded. He never tries in class, he wears his heart on his sleeve, he mouths off to me and other professors time and time again, and he torments the Slytherins. He thinks he is better than them because he is fighting the "good" fight, and he assumes that they are not.

In short, he is just like you. Maybe you do not realize your flaws, because your head has swelled so much that it doesn't allow blood to circulate to your minuscule brain. Yes, that is quite a possibility.

So... how's hell? Lots of fire? 'Cause I'll be joining you down there one day, unfortunately. Unless you're up in heaven. Unlikely...

So you married the Mudblood. I never got to comment to you on that. I thought that was a mistake, personally. It was bad enough that you were a blood-traitor, but you could have at least kept your lineage pure. And now we have the outcome of that union; an irritating, unintelligent, trouble-making, arrogant brat. Terrific. Bloody brilliant.

And then, of course, you go off and get yourself killed and leave the brat with his horrible relatives. Good move, Potter. I have no doubt that your son is abused.

Not that I care, of course.

I really don't see how Dumbledore can be so blind, just leaving the boy in your brother- and sister-in-law's care. Maybe you should write him a letter. Tell him to take the boy out. I'm not going to do it. Dumbledore has a way of twisting what you say and using it against you.

Well, that's pretty much it. There's not much left to write. Dumbledore's got this annoying smile on his face and this irritating twinkle in his eyes.

Severus S. Snape

Snape folded the letter, tapping it with his wand. He watched it disappear, before casting Dumbledore an irritated glance and leaving Number 12, Grimmauld Place.
