An empty classroom

Sandry saw a door standing half-open, with no one apparent on the inside. She rushed in, to find herself in a classroom.

"Oh, good." she looked around and realised she was alone. "Not good, as such. More, not terrible and humiliating at this exact second. Oh, cripes, now I'm talking to myself. Shut up, Sandry."

"Hey, this one's empty." a voice said from the corridor, too close. "Come on, guys."

Looking around, Sandry threw herself behind the teacher's desk, ducking out of sight just before a group of pupils entered the room. She heard at least six people, and a rustling of papers.

"Right," a voice said, "Who's got the yearbook layout pages?"

"Right here." came another voice.

"I've got the photo spread layout." came another, "But we've got a gap on page 23, it would be great to have a really popping photo for it."

"Let's see what we can do. Now, from page one."

Sandry sighed under her breath, trying to hold as still as possible. It sounded like they were going to be there for a long time.
