Waiting, waiting and waiting

Mom had knee replacement surgery this morning. We have been here since six this morning. Around noon the nurse here in the waiting room told me they'd move her out of recovery in about twenty minutes. It's now 3:30 and they haven't moved her to a room. She having trouble keeping her oxygen level up if she falls asleep, what I've been told, they won't let me in with her. I've used up my computer battery twice. The waiting room doesn't have any electrical outlets by the chairs. I am getting some quality editing time on my novel-in-progress.
