For those of you who were concerned (which is likely no one, since I totally forgot to mention this), Herb, my FIL, came through his surgery fine and was all right as of 8 last night.
He has his kidney removed yesterday because it had a 10cm growth on it. That's about the size of a tennis ball. They're going to send it to the lab to make sure it's not cancerous.
I mentioned to Steven yesterday that since, you know, I have pneumonia and he has a cold, that it would probably be better if he just called his father rather than going to see him. There are too schools of thought behind this. 1. Herb doesn't need Steven to come in, all covered in my pneumonia germs and 2. I don't need Steven coming home covered in all the hospital germs. Steven agreed, but his mother kind of complained.
She called back later and said that Steven better not visit his father if we're all sick here. I guess it makes it ok now that she thinks it was her idea.
