     The sun was just coming up when I headed out to work last May at 6 a.m. Not quite dark, but dark

enough to need my headlights. I turned onto one of the lonely, rural country roads.

     Maybe it was because I was listening to the radio, maybe it was because I was already thinking about

some projects at work, but I didn't spot the dark object on the road until it was too late. I ran over it and

felt the back left tyre pull, and then sink. I stopped and got out of the car.

     No mystery here-my back left tyre was cut like a loaf of bread. Back 50 yards was a piece of sharp

iron I'd run over. I've never changed a tyre. I looked up the road. Not a car in either direction. The nearest

service station was miles away. I threw up my hands. Then I remembered-my cell phone! I powered it up

before realizing, I didn't know who to call.

     Wouldn't you know it, I spotted a car coming from the opposite direction. The driver slowed as he

approached. I guess he could see I was in trouble. He stopped his car, got out and immediately saw the

trouble. "Madam, would you like me to change that tyre for you?" he asked. The man couldn't have been

more friendly. I was so frightened out there and he put me completely at ease. "There," he said, after putting

on the spare, "you're all set to go."

     "Good thing for me that you were driving this way," I told him, as I climbed back into my car.

     "Funny you should say that," he said. "Just like you, I was heading to work, but my job's in the opposite

direction. I made a wrong turn at some point. I don't know what I was thinking."
