Talked to Ma very very briefly over the phone today. She recognized me and asked how I was. I said, "fine and how are you!" She replied, "feeling strange," and then said something about the nurse coming in and hung up. I talked to my brother who said that now the doctors are not sure she even had a stroke. They now think the dizziness may have been caused by a drop in her blood pressure, which apparently is still low. They think the memory loss and disorientation may be more from the head injury. They don't know if she'll ever completely recover her short term memory and former mental function, but they do expect that she will recover about 90% of it. She is still in the hospital trying to build her strength back up for rehabilitation.
I made it into work today. I gave a final exam and graded it in my nice warm office. I hope our apartment is nice a cozy again when I go home presently.
