I thought I was teaching one class this evening, but I looked at my schedule and discovered that I was teaching 2 classes. Yikes! Fortunately, I’m in full teaching mode nowadays so suddenly teaching an extra class wasn’t too bad. I was a little punchy by the end of the night. Somedays I’d like to have a couple robot duplicates of myself, like Superman. That way, one of my robots could teach a class while I’m at home watching dvds.
