Poor Mom has caught a cold. :-( So she didn't really visit Dad today. He was sleeping when she poked her head into his room this afternoon, so she just wrote him a note that she had a cold and didn't want to give it to anyone.
I suggested that she might ask about trying a short visit tomorrow with a face mask, so he could see her for a little while anyway. Dad isn't big on socializing, but he is much more content when she is in the room, even though they don't talk much. That's how it has been for the last forty years. :-)
