Of course it has rules, silly! Genetically impossible? Nahhh!
I saw no evidence of rules. Looked a bit like rugby union - a giant game of "stacks-on"
And in all of those things that you did as a child, were competitive on their on level. The Orchestra kicked you out, huh? Why?
But given that it was right in the middle of university exams, and unlike most other people in the orchestra I don't actually study music at university I think I was at a bit of a disadvantage. Heh, my sister has decided to learn to play my flute so maybe I can force her to pay me for some lessons.
