Dad has been feeling "off" the past few days. Today he called and said he really wasn't feeling right, so I drove over and took him to the urgent care center near his house. Hours and hours later, they found he had the same sort of infection that landed him in the hospital last time. The doctor prescribed antibiotics, which will hopefully knock out the infection before he has a chance to get weak and confused, as he did last time. I'm glad I went over there so we could take care of the problem before it got worse, but I'm pretty darn tired now.
