A big audience!
I was sitting in the North-Hall in a break I had. I needed this break because I had so much work to do for school. I just started playing and I did not realise anything special until I heard the voices of people talking. I figured out that there were many parents sitting in the North-Hall and waiting for a parent meeting to begin. They told me to continue playing so I just continued and I think that they quite enjoyed it!:D
