When a car skidded on wet pavement and struck a telephone pole, several bystanders ran over to help the driver. A woman was the first to reach the victim, but a man rushed in and pushed her back. “Step aside, lady,” he barked. “I’ve taken a course in first aid.” The woman watched him for a few minutes, then tapped his shoulder. “Pardon me,” she said. “But when you get to the part about calling a doctor, I’m right here.”
