So they let gramps go home
Lots of tests were done etc etc. They finally sent grandpa home with grandma. I guess some test results won't be back until tomorrow, but they obviously didn't feel he was in any imminent danger or I'm sure they wouldn't have allowed him to go home. I'm not super relieved because I'd rather know what was or is wrong with grandpa, but I'm grateful he's well enough for now, and I won't waste time on worrying, because that helps nothing. Again, at least he's well enough to go home, so that's good.
