Todd, don't worry a bit about it. The lovely Mrs. Jones (Vita) was one day off all week last week, even though I kept telling her what day it was. She finally figured out that she was, indeed, one day off, and I think she's O.K. now. I think that's just one of the side effects of being "semi retired". You no longer have to work "Monday through Friday" so it makes no difference what day it is.
By the way, you're welcome here anytime too. You'll fit right in. We don't have a clue what day it is.
