This is not the instrument I used this morning to brush my teeth.
It is the instrument I used this morning to brush my hair, after my comb was
nowhere to be found. I had to use a toothbrush (from the travel bag
they gave me in the airplane) to brush my hair as I was tight on time to go downstairs to do a keynote, participate in a panel, and be interviewed
on film. (my hair didn't look any worse than usual, which is not saying much).
The next day I realized that I did have my comb after all. I had put it in the wrong compartment.
