Ma was much improved last night. We played Scrabble at the hospital*, and she was aware of who was dead and who wasn't, and was able to figure out her score for the most part.
She could not find her way back to us from the restroom, however, and I'm still not convinced she understands where she is. I think she thought we were at a party as we left, because she said goodbye to the nurses at the nurse station, announcing "I'll be back tomorrow!"
Leaving was tough. Ma, after saying all day she wanted to stay in the hospital, suddenly decided she wanted to go home. The nurse rushed us out the locked door to the wing as she ushered Ma into her room. As we were leaving, however, we heard a banging. We turned around to see Ma in the narrow window on the door, smiling at us and fumbling with the door handle, trying to get out. We waved but the nurse impatiently waved us on.
They have to keep her for a couple days with very limited visiting time to complete their tests.
