On one visit to Pakistan, Diana spent time with Imran’s sisters, Aleema and Rhanee, and in order to avoid press attention, they decided to drive themselves to the family’s home in the Model Town neighborhood of Lahore—Diana knew the address by heart. Stuck in a traffic jam, Aleema realized they were with the mother of the future King of England without bodyguards or drivers, “like sitting ducks.” As people began to recognize Diana, pointing toward the car and waving, “she was entirely unflappable . . . she rolled her window down, smiled, and waved.”
"To avoid press attention" - "she rolled her window down, smiled, and waved".
Does that make sense to you?
