Traffic was heavy on the service road to the airport. Our bus driver signaled to change lanes so he could overtake a slow-moving car. Just as he got ready to pass, the driver of the car put her arm out the window indicating she was going to move left. Our driver drew back and waited for her to change lanes but she didn’t. After a minute she pulled her arm back in.

When we tried to pass her a second time, the woman again held out her hand only to withdraw it a minute later. “C’mon, lady, make up your mind,” our driver mumbled. Finally, after four false starts, we sped past her car. I looked down to see the woman painting her fingemails. As she finished each nail, she waved her arm out the window to let the polish dry.
