Mom called this morning and said dad has pneumonia. Mom's sick and can't go visit because his white blood count is so low (although it's starting to increase a little because of the shots). I'll probably head back home to check on things here in a day or two.
Dad just called as I was writing this. He sounds a lot more congested than he did yesterday but was hopeful that the antibiotics would help him.
I'll keep you posted.
Have a good day.
