Hope he gets well soon... I know how completely unsettling that can be. Over the past 15 years, my father has averaged about two serious hospital visits a year. And it doesn't help that more than half the year he lives in Florida and is generally too stuborn to call and let us know. Evenyually his wife will defie his order and let us know. Once he called me and over the 5-10 minute conversation I overheard many hospital noises, but he never mentioned anything untill he was saying his goodbyes and I said, "Where are you, it sounds like a hospital or something."
Between his heart, lungs, diabetis, kidney failure and replaced hips and knees I've learned to treasure every chance I get to spend with him.
So anyway, I'll be thinking of you both.
