There I am taking the bus to work yesterday. It’s crowded, so everybody is sitting next to somebody. There are about 8 – 10 driver trainees on board, part of the reason for the fullness of the bus. I’m sitting next to one of the trainees, who is writing now and then in his notebook. Being the nosy bastard that I am, I naturally look at what he is writing. No surprise to discover that he is writing the directions for the route that we’re on. I go back to looking out the window for a few blocks, then boredom compels me to look again at his notebook. This is when I notice something odd. He has the route number (45) written on both the left and right pages. Not necessarily odd knowing that this route goes for an hour in one direction, then reverses for the next hour. But now I finally see what has been tugging at my subconscious… he has written the word “Left” at the top of the left-hand page, with “Right” being at the top of the other. Closer examination shows me that he is listing all the left hand turns on one page, and all the right hand turns on the other page. I so wish I could be on the bus the first time he tries to follow his own instructions.
