Nearly Headless Nick was just floating around when it happened. He was ghost, what else could he do other than scaring students like Peeves did?

Nick sighed as he wondered down the corridors sadly. He wished he was still human. Then he could live a normal life. He decided he would go to the Gryffindor common room to take a small break from doing - well, nothing. What was there to do anyways?

Halfway there he heard someone walking.

"Hello, is anybody there?" Nick called out. A Hufflepuff student appeared from around the corner. "Oh, I was just heading to my common room. Sorry I'll be out of your way," said the boy. Suddenly a look of horror struck his face, and he fell to the ground.

Nick turned quickly to see what the boy was looking at, and he too had a completely shocked expression afterwards.

He couldn't die again, though.
