And I closed it out, as usual with the Friday File. The markets have been recovering a bit as we all try to figure out what interest rates will look like next year, and when the economy might come out of what is presumably a recession, but none of that rates much of our attention — not because they aren’t important questions, but because we can’t really know the answers.
