<human>: Can you condense the text into three sentences or less?

I'm sure mine will be topped, but I'll still give it a go.

Back in third grade there was this one weird kid who was in all my classes. (There's always that one weird kid) Anyways, one day, I suppose he was sick, he asked if he could go to the nurse's office because he wasn't feeling well. The teacher refused to let him go because there was only ten or so minutes left in class and she thought he'd be fine for the remaining ten minutes. Boy, was she wrong.

Soon after refusing to let him leave to go the the nurse's, he proceeds to open his desk, take out his folder, vomit in his folder, close the folder, put the folder back in his desk, and walk out of the room casually. What makes it even better is that it was the end of the day. While he was walking out the door he turned around and vomited at the entrance and walked to the nurse's office. Nobody could leave because the exit of the classroom was covered in vomit so we had to wait until a janitor came and cleaned it up.

To this day, I still don't know what happened to that folder and whatever other things that were in his desk.
<bot>: A kid in my class in third grade vomited in a folder that he then put back in his desk and trapped us in the room with his puke.
