As far as I can tell it is mainly a precaution. However he was being repeatedly sick, he's elderly, frail and has a lot of conditions. I'm hoping he's out soon.
Also, we couldn't visit either him or have the much longed for visit with my brother as the car battery died (again) and the AA were some time coming out. We now have a new car battery.
On the bright side, we had a great time watching some YouTube videos together. These 'Top Ten Dumbest Tweets' had us laughing as we waited for the AA man. I also got some knitting done, we watched some episodes of the Flash and it could have been a lot worse.
So I'm keeping everything crossed for uncle and hope he's better soon.
