That was an interesting day. Having worked through the night (until 6 a.m.), trying to get something finished before I go away, I had a brief sleep and got into my office at 11 a.m. Of course, I was completely useless. Still, I managed to get an exam sorted out. (This is one of those things that's a remnant of semester one.) I also dealt with several potential problems by handing them on to someone else. Not so much delegation as a hospital pass.
I owe people quite a few favours now.
