I feel confused about that because we are going make something that we can't do it so maybe some people they can do it and some no. I can't do it until a few weeks for practice. I think I can't do it because I never dance like that or like American dancing. maybe It can be easy if everybody practice together  a lot that is way to learn how to dancing fast.  I think if we are going to do it the purpose will be each group has a leader.
