Yesterday's progress was measured with a big, round zero. Not a word, not a syllable. (And, believe me, there are days when a syllable would be appreciated.)
Things are going better today, but just barely. And the monster named Prior Commitments is waiting to kill my progress at any time.
These patches happen, though, and it is most important to just muddle through them.
After all, tomorrow is another day, as is Thursday.
