No, I've not given in to the September 10th mentality. But a September 12th mentality only works by comparison to what came before.
September 10, I was looking forward to starting a new contract, after having been looking for several months. As a last little exercise of my weekday free time, I got in the car, and drove up to Adams & Adams bookstore in Laramie to buy a book I had seen there earlier in the year. I can't even remember if I called ahead to see if they still had it.
Later, much later, I remembered the trip, but not the date. Not until I happened to open the book to the flyleaf, where I always write my name & when I bought the book, did I remember when I had had time to drive 2 1/2 hours to buy a book. The next day was a close-range bullet-hole in the calendar, spreading poweder burns backwards and forwards.
