My husband, a computer-systems trouble-shooter, rode with me in my new car one afternoon. He had been working on a customer’s computer all morning and was still tense from the session.

When I stopped for a traffic light, I made sure to leave a safe distance from the stop line to keep oncoming drivers from hitting the car.

I couldn’t help but laugh when my husband impatiently waved at me to move the car forward while saying, "Scroll up, honey."
