If I were you...

I was trying to get Darcy to go potty before dinner and she kept saying "But I'm playing and playing and playing" and she basically just ignored me. Finally I said, "Darcy. We are having hot chocolate after dinner tonight and you don't get any if you aren't a good listener, so if I were you, I would go potty and wash your hands right now." She replied (imagine it in a screaming voice):

"If I were YOU I would go potty and wash my hands!! But if I were ME I would NOT go potty and wash my hands!!!"
