Thank you. It is very nerve-wracking since they can't tell you how they feel at all. Papa had some issues a few years ago and we had no idea what was going on then. My sister likes to remind me how we thought we were going to lose him then, but he totally pulled through that time, so he may this time. I'm trying not to be too positive or too negative until I know for sure either way. Papa is home now. He seems really weak to me (not being very active all week has probably made the arthritis worse) but he gave me kisses and was purring, so even if he feels bad, he is happy to be home. That's something, right?
