The morning after the night before

I finally went down for surgery at 12.15am, and I'm guessing I was out for an hour or 2. I was really woozy when I got back to the ward, and high on oxygen (I like hard stuff).
I woke up around 5.30 needing to move position slightly, and see this in the bed opposite. It was the nurse changing a patients dressing, and the shadowy, night time blip couldn't be avoided!
