Let's me introduce myself : i'm the leader of the SportClub (tu peux bien évidemment changer!). So let me tell you the rules you have to follow.
You are not allowed to eat during matches, you must wear sportly shoes, a short and a white t-shirt, you can bring watter, if you want. For girls AND boys, you are not allowed to wear earring or some jewels [<< les bijoux].
And finally, you have to be good-tempered and enjoy this club!!
