Bat has his bad days and his good days. Just recently, he followed up a bad day with a markedly good day. Christa asked him what happened. He told her he had changed his underwear. I think clean underwear therapy is a direction medicine should look into.
...and then there's great days. Yesterday, Bat's doctor said he is cleared to drive. Gentle reader, I know you've heard me explaining Bat's terrible, terrible condition and his "Final Approach": the Pilot has spoken. Landing has been delayed.
