Today, I was at school in one of the smaller classrooms. There was about 7 of us in there. After about 5 minutes we can't stop laughing. We were making jokes and so on but it wasn't as funny as we thought it was.
I realised something was wrong, other people realised it to but did nothing.
I checked my pulse and my heart was beating rather slowly. I told every one but they didn't listen. I ran outside and get some fresh air. Everything seems much better. I go back to the room and the symptoms don't come back.
What was going on?
