I'm a student in a canteen. Someone asked me if I had spent the night with someone else and I said 'No I'm well behaved'. Then we were walking to the first lesson (I think it was geography), I was carrying 2 books, and I realised I had the wrong ones. We walked into a building and I had to throw something away, the teacher was watching and looked a bit annoyed that I was veering off but was ok once he saw I was just going to the bin.
The classroom was at the top of a very tall steel framed structure, the staircase was spiral. The top was open to the air. We had to queue at the top, it was frighteningly high. We held the door open for the teacher, he had to step over a coat that someone had left. I ended up holding the door as everyone went in even though I had been first in the queue. 2 girls decided they were going over the edge they didn't feel well and weren't going to the class. It was really high, I could see mountains in the distance, I thought they were mad and helped lower them over the edge.
