So, I bought the book, with autograph, at the game yesterday. Unfortunately, I left it at the concession stand at halftime, so somebody got a free copy.
I told Bill about this after the game, told him I was willing to pay for another one, and he gave it to me, free of charge. No autograph this time, but that's no big deal. He didn't have to do that. It was a classy move on his part.
