The official word is Dad let himself get dehydrated. He has now been told but someone in a white coat, with clipboard, that 28 ounces of water a day is not enough. [Note that my mother has been saying that for quite some time. She just "isn't a doctor." My father can be a elitist prig from time to time.]
They are keeping him for another night to pump him up with IV fluids. He's flirting with the nurses and whatnot, so he should be alright.
We did manage to find all of my siblings yesterday, finally. It's like herding cats to reach them all.
Thank you to everyone who sent kind thoughts and prayers our way. I appreciate it more than you know.
The regularly scheduled minis, sewing, and musings will return sometime tomorrow.
