Nobody Came Back

The mayor visited my school. He had asked for one class at a time. First, the youngest and so on. I had got into trouble before he had wished for our class. I was talking in class, worst of all I was asking for the answers to the test. I was the last person to see the mayor.

Everyone else had gone and it was my turn to see him. But nobody was there!
I went around all the classes and not one child, nor adult was sitting at a desk. I needed to find out what was going on, and more importantly... What was going to happen to me?
