Half-Painted Room, Moved Stuff, Irritating Night...

Bought paint over the weekend to have my room painted this coming weekend. Was surprised when my Mom informed me that she already had the room painted today. Was even more surprised (irritated, actually) when she told me she moved stuff out of my room without my permission. Came home to a room half-painted in baby blue color. Apparently, the paint we bought wasn't enough to cover the entire room.
