But it wasn't most of the night, Sia and Michelle danced off and on for nearly 2 hours. There's simply no point in getting so worked up (not you corbo but others) at these girls because we have no way to know the circumstance. They could have been like hey Sia come hang with us outside and Sia said no thanks I'm going to keep dancing. I mean who knows, my guess is they will be all smiles in the morning and this will be a positive start for Michelle and Sia.
