I was cruising along the sidewalks of downtown Seattle, trying to get back to my place of business after an unduly long lunch break. As I careened around a corner I bumped into a young guy who was standing there talking to his friends. As I was in hurry I did not stop, but I did look over my shoulder and cry “sorry!” As I did so, I saw that the guy was angry: his eyes were narrowed, he was pointing a finger at me, and he was opening his mouth to say something ugly. I guess he didn’t expect me to apologize. But as soon as I did, a remarkable transformation overcame him. His whole body abruptly relaxed, his accusatory finger went flaccid, and instead of wrath his face suddenly filled with the look of a man who has just had an epiphany. I could see the muscles around his mouth frantically reconfiguring themselves as he completely changed was he was about to say. Since I had been in motion this whole time, I was pretty far away when he finally managed to speak.
“Keep your tools sharp,” he shouted.
With a nod I faced forward and continued on my way.
