Worked early at Java this morning, passing through fog so thick I almost hit the brights.  (Crossing over the James White Parkway bridge, I emerged from the huge fog bank like a red bullet.  Clear blue heights, morning lights.)  Wrote responses, sent emails, was responsible for about two and half hours.  Then back over the bridge, to be exhausted in my apartment.  It is so exhausting, yesterday and today, and tomorrow and Friday.  This entire day is filled with wishing already, pressing heavily against the borders of waking and sleeping.
