The Fan girls

Severus Snape was annoyed. He was sitting in a hot, filthy bus with more than fifty noisy children behind him. Directly beside him sat the smiling, cheerful Albus Dumbledore.

"Let's sing another song!" The old man announced. "The wheels on the bus go round and round, round and round, round and round!"

The students eagerly joined in, and Severus couldn't help but groan.

"Albus, are you sure this is completely necessary?" he asked, rubbing his temples.

"Of course it is! What better way for the students to learn muggle studies than to visit the muggles?"

Severus shook his head and stared out of the window.

About an hour later, they arrived. Severus was the first one out of the bus, his Slytherins quickly following behind him.

"What was that?" Draco whined, his face green. "Why do muggles use that ugly yellow machine? It takes hours to get somewhere, and it smells!"

"The night bus is much faster." Blaise agreed, then paused to put his hand over his mouth as he almost gagged.

"Muggles?" a voice asked excitedly.

Everyone froze. A muggle had overheard their conversation. Severus glared at his students before turning to the woman.

"I think you misheard, Miss," he explained. "No one said – what was that word – muggies?"

"Oh, I think they did…Professor Snape." The red head grinned widely, her eyes bright.

Severus immediately relaxed.

"You're a witch." He breathed.

Everyone immediately relaxed and began chatting again, careful not to mention anything magical incase muggles were near.

"Who are you? Are you following us?" Severus asked suspiciously.

"I don't know why you assumed I was a witch." The woman whispered, practically bouncing from one foot to another. "I'm not. I just read this."

She fished in her bag and pulled out a book. Severus quickly snatched it, paling when he read the cover.

Harry Potter and The Sorcerers Stone.
