I had hoped that I would be able to make it back from Colombia without bringing back a nasty bug; in 2003, on our first visit, I came home with a dreadful case of giardia. I was fine yesterday in the first few hours after arriving home, but last night became violently ill. No hospital trip, just the usual unpleasantnesses. It's only now, at just before 4:00PM, that I'm up and showered and feeling somewhat civilized.
To my students in my Wednesday classes, I apologize for another missed day. And to my readers, I promise to be posting again relatively soon.
