Happy Birthday, Sir

My name is Severus Snape, Potions Master at Hogwarts School of Witchcraft and Wizardry. I am not in a good mood right now. It is my bloody birthday, and all of the staff have been wishing me a happy birthday, even though I don't care about it. The bloody Head of Gryffindor House even tried giving me a birthday present. She got me potion ingredients, but they were the ones I already had. I wanted new ones. Stupid Gryffindor. She's a dunderhead.

It did not help that this morning, Longbottom just had to blow up his cauldron. That boy doesn't know how to do anything right. I made sure to take fifty points from Gryffindor for that. Then the Granger girl tried wishing me a happy birthday, so now every student knows about my blasted birthday. Stupid girl. I bet Minerva told her that it was my birthday just so more people could get on my nerves.

Ever since then, students have been coming to my office to wish me a happy birthday. I DON'T CARE! The only person that has ever been allowed to wish me a happy birthday was... No, I'm not even going there.

I'm sitting at my desk, grading essays. Bloody hell! Does the Granger girl even know how to stop writing? I'm not going to take three hours to read through a fifty foot essay. I'm just going to give her a T. I'm hoping that no one else comes to my office this evening, because if they do, I'm going to throw something. No one crosses me when I'm in this mood.

There is a knock on my office door. Seriously?! I growl as I get up to answer it.

"Potter," I say in annoyance. "What do you think you're doing here? You don't have detention with me, so if you have a problem, go to Professor McGonagall."

Potter looks slightly scared. "Er... happy birthday, Sir," Potter says. I sneer at him.

"I don't want to hear it," I say. "Only come to my office if I order you to. Goodbye, Potter." I go to slam the door, but Potter puts his foot in the door.

"But Sir, don't you like your birthday?" Potter asks.

"No, Potter, now get out!" I yell.

"Sorry, I'll go now," Potter says. He steps out, and turns around and says, "Again, happy birthday, Sir." He quickly runs off. I slam the door shut, and stomp to my desk, and throw a book against the wall.

"Stupid brat!" I yell, before sitting back down to continue grading. Gryffindors would be the death of me.
