I was driving to my friend’s memorial service when rows of taillights began braking in front of me. I flipped on the radio and learned that traffic was backed up because of an accident miles ahead. I lurched and stopped for 10 minutes . . . then 20. Now I was late. I thought about turning around and going home. But then it occurred to me that sticking it out would be the best way to show that I cared. I didn’t know if I would make it to the service, but every minute of my forced waiting would express my devotion to my friend.
