Severus stalked around the dungeons, pudding cup in hand. He was avoiding everyone today, and as it was Saturday, that was pretty easy to do. He hadn't even gone up to meals because he was dreading what would happen if he did. Yes, today was his birthday.
As soon as Severus had woken up, he stole to the kitchen and frightened the house elves into giving him pudding. Lots of pudding, to last him the whole day locked up if he needed to.He remembered all too well what happened last time he made a public appearance on his birthday. Albus had gotten the whole school to sing to him with those pointy little party hats on and Severus was forced to pass out cake to the entire school, with his own little pointy party hat on—a black one.
So here he was, on his birthday, hiding out in the dungeons with a ton of pudding and making a run for his personal quarters, hoping against all hope that he wouldn't meet—
"Happy Birthday Severus!" said Albus Dumbledore as he walked down the hall towards him. He had that twinkle in his eye that meant he was up to something. "I hope you are well?"
Severus had an idea. "Actually, no, Albus. I'm feeling dreadfully tired! I've been so excited to see what you had planned for my birthday today that I could barely sleep!" he lied with a little frown for emphasis. He wanted more than anything to just get back to his quarters and fall into a pudding binge.
Much to his surprise, Albus just nodded his bearded head and told Severus to feel better. Sighing with relief, Severus walked the last few yards to his quarters. Muttering a password under his breath, the door sprang open and Severus walked inside. It was dark.
"SURPRISE!" A dozen faculty members and ghosts sprang out from behind various pieces of furniture as the lights suddenly came to life. But the lights weren't on long for Severus: he hit the ground before you could say, "Happy Birthday" and was out cold, the pudding cup falling from his hand and rolling silently away on the floor.
